How can i get the image if I was given a URL with lots of img src? I am using Laravel 5.2.
This takes too long to load given that I have 6,000 links. Thanks in advance.
$url="$products->product_url";
$html = file_get_contents($url);
$doc = new DOMDocument();
#$doc->loadHTML($html);
$tags = $doc->getElementsByTagName('img');
foreach ($tags as $tag) {
echo $tag->getAttribute('src');
}
Firstable you need to find some kind of class of id of parent element that contain image that you need for example:
<body>
// bla-bla-bla
<div class="content">
<img src="img.png" />
</div>
</body>
You can do follow with ZendDomQuery:
$finder = new Zend_Dom_Query($html);
$node = $finder->query("div[class~='content'] img");

I am trying to build a joomla template and would like to include an image upload option for users to upload custom images for a logo.
Currently I have this structure:
In my templateDetails.xml:
<config>
<fields name="params">
<fieldset name="basic">
<field name="logofile" type="media"
directory="images"
label = "Logo"
description ="Choose a logo"/>
</fieldset>
</fields>
</config>
Then in my index.php:
// Getting params from template
$params = JFactory::getApplication()->getTemplate(true)->params;
$app = JFactory::getApplication();
$doc = JFactory::getDocument();
$this->language = $doc->language;
$this->direction = $doc->direction;
// Detecting Active Variables
$option = $app->input->getCmd('option', '');
$view = $app->input->getCmd('view', '');
$layout = $app->input->getCmd('layout', '');
$task = $app->input->getCmd('task', '');
$itemid = $app->input->getCmd('Itemid', '');
$sitename = $app->getCfg('sitename');
$logo = $this->params->get('logo');
Then further down in my body I try to output the $logo variable but It displays nothing on the screen....
<a href="<?php echo $this->baseurl ?>/templates/<?php echo $this->template; ?>/<?php echo $logo;?>
Anyone know where I might be going wrong?? Much appreciated for any help or advice.
EDIT
Made some progess.
when I upload images they are being stored in the default images folder in the joomla directory. I copied the image across to my templates image folder and managed to get it to display using this:
<img src="<?php echo $this->baseurl ?>/templates/<?php echo $this->template; ?>/images/logo2.png"
however it is not dynamic as $logo is not being used. It does not seem to be assigned any value at all.
Hi, I use a php code to view the all comments to any post from my sql and I want to add a submit button to every comment in order to delete it without refreshing the page, I mean using AJAX i don't know how to write that codes and connect it with html codes i want add submit like this :
<form>
<input type="submit" id="deletecomment">
</form>
and connected it with AJAX and delete.php page to delete the comment (ajax,delete.php)???????
this is my codes
$result = mysql_query ("select * from post_comments WHERE link ='$getlink' order by link asc");
while ($row = mysql_fetch_array($result)) {
$id = $row['id'];
$link = $row['link'];
$time = $row['time'];
$content = nl2br($row['content']);
$name = ($row['link'] != '') ? '<h3 style="color:blue">'.$row['name'].'</h3>' : $row['name'];
$imge = $row['imge'];
echo '
<div class="commentuserbackground">
<img src="'.$imge.'" width="30px" height="30px">
<div id="comment-'.$id.'" class="username1">'.$name.'</div>
<div class="username2">'.$content.'</div><div class="commenttime"><h4 style="color:#5a5a5a">'.$time.'</h4>
</div></div>';
}
If you already have the jquery lib included in your html, you could do something like this:
# html page
<button data-id="1" class="delete_comment" /> # no need to wrap in form
# At the bottom of the body tag
$(".delete_comment").click(function(e){
e.preventDefault();
var $button = $(this), $comment = $button.parent(), id = $button.data("id");
$.ajax({
type: 'DELETE',
url: "/path/to/comment/" + id,
success: function(){ $comment.remove(); }
});
});
I have php file called testfun.php. Which is getting values from the databse
<?php
$conn=mysql_connect("localhost","root","") or die("unabke to connect");
$db=mysql_select_db("smartyform",$conn) or die("databse error");
require 'Smarty/libs/Smarty.class.php';
$smarty = new Smarty;
$sel=mysql_query("select * from form");
while($row=mysql_fetch_array($sel))
{
$id=$row[0];
$name=$row[1];
}
$smarty->assign('id',$id);
$smarty->assign('name',$name);
$smarty->display('testfunction.tpl');
?>
I have tpl file called testfunction.tpl. I am getting output in this file
<body>
<ul>
{$id}
:
{$name}
</ul>
</body>
</html>
When I run the testfun.php I got this output:
16 : dg
But I want output like:
1:d
d:g
What should I do ?
Store your data in an array. So you have to do a for loop in your tpl.
It would be like this in your tpl:
<ul>
{foreach from=$your_data item=item_value key=key}
<li> { $key } : {$item_value}</li>
{/foreach}
</ul>
In your php make it this way:
require 'Smarty/libs/Smarty.class.php';
$smarty = new Smarty;
$your_row= array();
$sel=mysql_query("select * from form");
while($row=mysql_fetch_array($sel))
{
$your_row[]= $row;
}
$smarty->assign('your_data',$your_row);
$smarty->display('testfunction.tpl');
?>

Hope that helps you.
I have a custom block loading products on my front page that loads the four newest products that have a custom product picture attribute set via:
$_helper = $this->helper('catalog/output');
$_productCollection = Mage::getModel("catalog/product")->getCollection();
$_productCollection->addAttributeToSelect('*');
$_productCollection->addAttributeToFilter("image_feature_front_right", array("notnull" => 1));
$_productCollection->addAttributeToFilter("image_feature_front_right", array("neq" => 'no_selection'));
$_productCollection->addAttributeToSort('updated_at', 'DESC');
$_productCollection->setPageSize(4);
What I am trying to do is grab the image_feature_front_right label as set in the back-end, but have been unable to do so. Here is my code for displaying the products on the front end:
<?php foreach($_productCollection as $_product) : ?>
<div class="fll frontSale">
<div class="productImageWrap">
<img src="<?php echo $this->helper('catalog/image')->init($_product, 'image_feature_front_right')->directResize(230,315,4) ?>" />
</div>
<div class="salesItemInfo">
<p class="caps"><?php echo $this->htmlEscape($_product->getName());?></p>
<p class="nocaps"><?php echo $this->getImageLabel($_product, 'image_feature_front_right') ?></p>
</div>
</div>
I read that $this->getImageLabel($_product, 'image_feature_front_right') was the way to do it, but produces nothing. What am I doing wrong?
Thanks!

It seems you asked this same question in another thread, so to help others who might be searching for an answer, I'll anser it here as well:
I imagine this is some sort of magento bug. The issue seems to be that the Magento core is not setting the custom_image_label attribute. Whereas for the default built-in images [image, small_image, thumbnail_image] it does set these attributes - so you could do something like:
$_product->getData('small_image_label');
If you look at Mage_Catalog_Block_Product_Abstract::getImageLabel() it just appends '_label' to the $mediaAttributeCode that you pass in as the 2nd param and calls $_product->getData().
If you call $_product->getData('media_gallery'); you'll see the custom image label is available. It's just nested in an array. So use this function:
function getImageLabel($_product, $key) {
$gallery = $_product->getData('media_gallery');
$file = $_product->getData($key);
if ($file && $gallery && array_key_exists('images', $gallery)) {
foreach ($gallery['images'] as $image) {
if ($image['file'] == $file)
return $image['label'];
}
}
return '';
}
It'd be prudent to extend the Magento core code (Ideally Mage_Catalog_Block_Product_Abstract, but I don't think Magento lets you override Abstract classes), but if you need a quick hack - just stick this function in your phtml file then call:
<?php echo getImageLabel($_product, 'image_feature_front_right')?>
Your custom block would need to inherit from Mage_Catalog_Block_Product_Abstract to give access to that method.
You could also use the code directly from the method in the template:
$label = $_product->getData('image_feature_front_right');
if (empty($label)) {
$label = $_product->getName();
}
how to get the name of the file and the content type of the image which we uploaded in mvc application please tell me its urgent
thanks
