I'm experimenting with Wordpress and (the recent version of) dompdf at the moment and ran into an annoying problem regarding the formating.
My Problem: The top-margin of the main content seems not to be considered on the second page generated, resulting in an overlapping with my logo. You can view the generated PDF under this link.
The relevant code from which the PDF is generated reads as follows (it is not perfect yet as i want to resolve the issue first):
function ppt_pdf_output() {
// post-ID of referring page needed
$post=get_post($_POST['postid']);
$output = '<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>'.$post->post_title.'</title>
<style>
body {
margin: 30px 0 0 0;
font-family:sans-serif;
text-align:left;
}
img {
margin: 15px 0;
}
#header,
#footer {
position: fixed;
left: 0;
right: 0;
color: #aaa;
font-size: 0.9em;
line-height:1.2em;
}
#header {
top: -30px;
/*border-bottom: 0.1pt solid #aaa;*/
}
#footer {
bottom: 0;
border-top: 0.1pt solid #aaa;
}
#header table,
#footer table {
width: 100%;
border-collapse: collapse;
border: none;
text-align: center;
color: #000;
font-size: 24px;
}
.entry-content {
margin: 100px auto 35px auto;
top: 0; left: 0; bottom: 0; right: 0;
background-color: #d1d977;
width:90%; height:auto;
}
.entry-title {
font-size: 18px;
text-align: center;
}
#header td,
#footer td {
padding: 0;
width: 50%;
}
#footer .page-number {
text-align: center;
}
.page-number:before {
content: "Seite " counter(page);
}
.gallery-item {
display:inline-block;
}
br[style] {
display:none;
}
.gallery + p {
clear:left;
}
</style>
</head>
<body><div id="header">
<table>
<tr>
<td>ANTRAG</td>
<td style="text-align: right;"><img src="path/to/logo.png" /></td>
</tr>
</table>
</div>
<div id="footer">
<div class="page-number"></div>
</div>';
$output .='
<!--<h1 class="entry-title">'. $post->post_title .'</h1>-->
<div class="entry-content">' .
apply_filters('the_content',$post->post_content) . '</div>';
$output .= '</body></html>';
return $output;
}
As you can see, the formatting on the first page is as it should be (or at least as I intended it to be), but after the page break the content area (for visualization reasons provided with a green background) just starts at the beginning of the page, regardless of which number I give the margin.
Has anybody an idea how to resolve this issue? I've been working on this for countless hours and just don't know what to do at this point.
Any help would be greatly appreciated.
Kind regards
Olli
UPDATE: Of course I found this solution only just. I will try this and see if I can get the issue resolved with this.
UPDATE2: Still no luck. I'm now stuck with the following code (the output can be found under the link provided earlier):
function ppt_pdf_output() {
// post-ID of referring page needed
$post=get_post($_POST['postid']);
$output = '<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>'.$post->post_title.'</title>
<style>
#page {
margin: 120px 50px 80px 50px;}
#header {
position: fixed;
top: -82px;
width: 100%;
height: 109px;
background: #aaa url("path/to/logo.png") no-repeat right;
}
#content {
width: 100%;
height: 85%;
background-color: #d1d977;
}
footer {
position: fixed;
bottom: -65px;
height: 30px;
background-color: #333399;
}
footer .page-number {
text-align: center;
}
.page-number:before {
content: "Seite " counter(page);
}
br[style] {
display:none;
}
</style>
</head>
<body><div id="header">
<h2>ANTRAG</h2>
</div>
<footer>
<div class="page-number"></div>
</footer>';
$output .='<h1>'. $post->post_title .'</h1>
<div id="content">' .
apply_filters('the_content',$post->post_content) . '</div>';
$output .= '</body></html>';
return $output;
}
It seems just so fragile. For example, as soon as I change the font-size of the h1 element, it gets overlapped by the logo. After the page break, it looks okay, but that just seems an coincidence - as soon as I change the font-size or the text, the text again gets overlapped. Will absolute positioning change anything or do you have any other tipps as how to resolve this anoying issue? Margins of any kind don't seem to work either.
You're on the right track. As you've seen, when an element is split across pages (as your content area is) some of the formatting information does not follow. This is by design.
The correct tact is to define the page margins so that they are large enough to hold your header/footer content and place the header/footer into that space. The content will then just fill the "body" of the document (i.e. the space inside the page margins). This is what you've attempted, but you haven't given enough space for the header. The header is positioned 82px inside the page margin but the height of the header is 109px. Because of this any content that has a small margin will still fall under the header.
Try this instead:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>"Kaffeefahrten" in Bornheim: hart durchgreifen, Senioren vor Betrügern schützen</title>
<style>
#page {
margin: 120px 50px 80px 50px;
}
#header {
position: fixed;
top: -115px;
width: 100%;
height: 109px;
background: #aaa url("path/to/logo.png") no-repeat right;
}
#content {
background-color: #d1d977;
}
footer {
position: fixed;
bottom: -65px;
height: 30px;
background-color: #333399;
}
footer .page-number {
text-align: center;
}
.page-number:before {
content: "Seite " counter(page);
}
br[style] {
display:none;
}
</style>
</head>
<body>
<div id="header">
<h2>ANTRAG</h2>
</div>
<footer>
<div class="page-number"></div>
</footer>
<h1>"Kaffeefahrten" in Bornheim: hart durchgreifen, Senioren vor Betrügern schützen</h1>
<div id="content">
...
</div>
</body>
</html>
Note that you also don't have to specify any height/width for the content element (unless you want to further constrict the space it uses).
With CSS3 you could go with your original styling and re-use the margins by applying the box-decoration-break property. However as of writing dompdf does not yet support this property.

I have an issue with Dompdf not positioning images correct.
The output in browser is ok, but the images are to close to the title in the PDF.
They should also render over the blue bar. I thought this should be possible with either a negative margin-top or a position absolute. But from what I read is that position:absolute inside a position:relative container is (still) not working.
HTML and expected output:
<html>

PDF renders as follows:

PHP Code:
$dompdf_options = new \Dompdf\Options();
$dompdf_options->set('isRemoteEnabled', true);
$dompdf_options->set('chroot', $dirname);
$dompdf = new \Dompdf\Dompdf($dompdf_options);
$dompdf->loadHtml($html);
$dompdf->setPaper('A4', 'portrait');
$dompdf->render();
$dompdf->stream();
This is an issue with how Dompdf aligns element within a line box. There is an ongoing effort to address the issue (WIP).
With the current release you can work around the issue by moving your image block down using relative positioning. You'll also want to set z-indexing a bit differently to better accommodate how Dompdf renders elements.
Try the following:

I am trying to create a pdf report using dompdf. The report needs to have the company logo on the top of the first page as well as a header and footer on every page. I have found solutions for adding a header and footer to a dompdf document elsewhere on stackoverflow. The problem I'm running into is that the company logo needs to be above the page header on the first page and not displayed on other pages
something like this
Company Logo
- header
- content here
- footer
------
- header
- content here
- footer
Is there any way of doing this using dompdf?
This is kludgey, but it works. You can basically fake the different headers by creating a normal header using fixed positioning and the special page 1 header using absolute positioning. If you set things up in the right order the page 1 header will be rendered on top of the standard header, obscuring it.
<html>
<head>
<style>
#page {
margin: 0px;
}
#page :first {
margin-top: 100px;
}
body {
margin: 100px 20px 50px 20px;
}
#headerA {
position: fixed;
left: 0px; right: 0px; top: 0px;
text-align: center;
background-color: orange;

}
#headerB {
position: absolute;
left: -20px; right: -20px; top: -200px;
text-align: center;
background-color: orange;
height: 190px;
}
#footer {
position: fixed;

height: 40px;

I have a table with absolute positioneg paragraphs inside <p>. It renders as I want it to in Chrome and Opera, but in Firefox all the numbers are outside the table and crammed together. I've tried adding position: relative; to all parent element, but it didn't help much. Where's the problem? I quess it's something simple.
That's how it looks: http://i50.tinypic.com/34diewz.png (I'm a new user, can't upload images yet)
Also these <p>'s must be postitioned absolute, because there are other element in table cells in full project - this code is just a small part. Here it is:
<!DOCTYPE html>
<html>
<head>
<style>
* { margin: 0; padding: 0; } /* Just a quick reset, I use proper one in full project */
table {
background-color: #296B73;
}
td {
position: relative;
height: 40px; width: 40px;
border: 1px solid #0F2D40;
}
p {
position: absolute;
top: 28%; left: 50%;
margin-left: -5px;
}
td:nth-child(1) { width: 50px; }
td:nth-child(2) { width: 75px; }
td:nth-child(3) { width: 100px; }
</style>
</head>
<body>
<table>
<tr>
<td><p>1</p></td>
<td><p>2</p></td>
<td><p>3</p></td>
</tr>
<tr>
<td><p>1</p></td>
<td><p>2</p></td>
<td><p>3</p></td>
</tr>
<tr>
<td><p>1</p></td>
<td><p>2</p></td>
<td><p>3</p></td>
</tr>
</table>
</body>
</html>
You can't relative position TD's so instead you need to put an surrounding container for the P's:
<td><div><p>1</p></div></td>
<td><div><p>2</p></div></td>
<td><div><p>3</p></div></td>
Then in CSS:
td div { position: relative }
Below code display the list populated from database(DB code is not included). If I click on the search results, then the selected option will not show in textbox. Help please.
Below code works fine to show list of options from Database while typing characters. The issue is it will not show the selected drop down option into textbox.

In this line
$('#autoSuggestionsList').html(data);
you are setting some html that I assume consists of a list of div tags with your auto-suggestions. If you want the user to be able to click on the list, you need to have a click handler attached to the suggestions that loads the value. Like
$(document).ready(function() {
$("#autoSuggestionsList div").on("click", function() {
//put your click actions here.. load the textbox, hide the list
});
}
The on command is live, meaning it will automatically be bound to elements that are loaded dynamically.
EDIT
Since you're using li instead of div, change the above to
$(document).ready(function() {
$("#autoSuggestionsList li").on("click", function() {
fill($(this).text());
});
}
EDIT 2
In the new code you added, this line is incorrect
out.println("<li onclick='fill("+rs.getString("EMP_FNAME")+");>"+rs.getString("EMP_FNAME")+" </i>");
It will produce incorrect HTML/Javascript that looks like this:
<li onclick='fill(some text);>some text</i>
Your code should look like this:
out.println("<li onclick='fill(\""+rs.getString("EMP_FNAME")+"\");'>"+rs.getString("EMP_FNAME")+" </li>");
It will produce the following correct HTML/JavascriptL
<li onclick='fill("some text");'>some text</li>
This code works in every other browser I've tried, except IE8.
IE8 appears to ignore the z-index - and the pop-up becomes a pop-under.
It's in the right place, just renders underneath the thumbnail.
Anyone?
Thanks!
HTML:
<a class="thumbnail" href="#thumb">
<img src="comic_a3_thumb.jpg" height="300" width="212" border="0"
style="float:right; margin-top:10px;margin-bottom:10px;"
alt="description" />
<span>
<img src="/images/comic_a3_popup.jpg" />
</span>
</a>
CSS:
.thumbnail{
position: relative;
z-index: 0;
}
.thumbnail:hover{
background-color: transparent;
z-index: 50;
}
.thumbnail span{ /*CSS for enlarged image*/
position: absolute;
background-color: lightyellow;
padding: 5px;
left: 0px;
border: 1px dashed gray;
visibility: hidden;
color: black;
text-decoration: none;
}
.thumbnail span img{ /*CSS for enlarged image*/
border-width: 0;
padding: 2px;
}
.thumbnail:hover span{ /*CSS for enlarged image on hover*/
visibility: visible;
top: -140px; /*position where enlarged image should offset horizontally */
left: -500px;
}
The simple answer is to add a z-index value that is greater than the .thumbnail:hover value to the hover state of the span.
.thumbnail:hover span{ /*CSS for enlarged image on hover*/
visibility: visible;
top: -140px; /*position where enlarged image should offset horizontally */
left: -500px;
z-index: 51;
}
Put these lines in your page head
<!--[if IE]>
<style>
#your_faulty_div{
background-color:#000; /*any color it doesn't matter*/
filter: alpha(opacity=0);
}
</style>
<![endif]-->
your_faulty_div is the div which is misbehaving due to IE z-index bug.
Works smooth , i use it in all of my projects where i have positioned elements overlaping.
If I understand you correctly, you want the span to show above the element marked as the thumbnail. You have not specified the z-index for the span element. Here is a working example:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=UTF-8" />
<title>Pop-up Test</title>
<style type="text/css">
#vbox {
border: 1px solid black;
height: 200px;
position: relative;
width: 200px;
z-index: 0;
}
#vbox:hover #hbox {
display: block;
}
#hbox {
border: 1px solid blue;
display: none;
height: 200px;
left: 50px;
position: relative;
top: 50px;
width: 200px;
z-index: 1;
}
</style>
</head>
<body>
<div id="vbox">
<p>Hover over this box to show a hidden "pop-up".</p>
<p id="hbox">This box is a pop-up.</p>
</div>
</body>
</html>
The way to fix this issue is by adding a class to the thumbnail image like this:
.thumbnail:hover img.thumb {z-index:-50; position:relative;}
