in the next page i am getting till "Hi all"
Remaining text is missing, If I pass through get or post method using ajax.
Give me the solution. How to get all the content I placed in text box along with "&"


You need to urlencode string with escape or encodeURIComponent functions.


Yes, I have faced same type issue and find out solution that we need to pass data as a key value pair,
I had passed data in Ajax like:
data : email=" + email + "&name='" + name
But right way for passing data in Ajax is :
data: {
email : email,
name : name
}

If one of my POST Parameters contains character '+' it gets converted to ' ' instead of passing it correctly

When passing the id "vpzYeZkOy4HpNo + DLBb4WQ ==" disappears "+" in the body of id.

Can you try passing + as a URL encoded value => %2B?
Edit: #David beat me to it

Search Query Parameter

I want to search email which contains '+' in it. for example
something like this myemail.subdomain+1#domain.com.
URL - https://example.com?searchKey=myemail.subdomain+1#
I am using Laravel, this parameter is fetched from route using
$request->get('searchKey');
but it's converting '+' to ' ' ,
as a result i am getting
searchKey as myemail.subdomain 1#
which leads to improper result.
Any help?

PHP assumes that + from GET request is a space. Right encoded plus symbol is %2B.
You have to just prepare string from request to save plus symbol:
$searchKey= urlencode(request()->get('searchKey'));
In your case you'll get # as %40. Then you can replace plus with correct code and decode it. But then be careful with usual spaces!
$searchKey = urlencode(request()->get('searchKey'));
$searchKey = urldecode(str_replace('+', '%2B', $searchKey));
https://www.php.net/manual/en/function.urlencode.php
https://www.php.net/manual/en/function.urldecode.php
P.S. I suppose it is not the best soulution, but it should work.
P.P.S. Or, if you can prepare plus as a %2B before it will be at search parameter, do it

Can't send '+' character over ajax

I have a script that makes an ajax request passing 3 different data : eventName / ticketsToWin / totalWinners.
My whole process was working perfectly until I had this case : "SCi+Tec" as the eventName variable. Here is what looks like the data of the request just before sending :
name=Sci+Tec&ticketsToWin=1&totalWinners=2
But then, on the PHP side, if I dump the _GET array, I have this :
array(4) {
["name"]=> string(7) "Sci Tec"
["ticketsToWin"]=> string(1) "1"
["totalWinners"]=> string(1) "2"
["_"]=> string(13) "1372359516001"
}
The '+' character is missing in the name, which breaks everything that comes after. Any idea why ?!
Thans!

encode your string:
name=Sci%2BTec&ticketsToWin=1&totalWinners=2
Or easier:
var str = 'name=Sci+Tec&ticketsToWin=1&totalWinners=2';
var encoded = encodeURIComponent(str);
see the docs or this Question

I'm pretty sure that the plus sign in URLs is used instead of a space, like in a google search, you give the following query:
"How to send an email",
It will show in the URL as:
"How+to+send+an+email".
Try POSTing it.

In Urls, spaces in query strings are automatically replaced by plus signs. So when the server gets Sci+Tec, it thinks there is supposed to be a space there. You will need to escape it with its url encoding: %2B.
More on Url encoding: http://www.w3schools.com/tags/ref_urlencode.asp

you could either use a java url encode or a javascript encoder
URLEncoder.encode(yourString)

Can an empty URL parameter be passed to my controller?

Let's say my controller function is expecting 2 parameters: page_name, and user_name
The URL would be in the format http://mysite.com/controller_name/function_name/page_name/user_name
Assuming that sometimes I can have a blank user_name, and other times I can have blank page_name, can I pass a blank page_name by loading this URL?
http://mysite.com/controller_name/function_name//user_name
If the controller function is:
function function_name($page_name="default", $user_name=null)
...
Would the $page_name value be "default" for the 2nd URL stated above?

You can't. Server will simply ignore the extra slash.
Since both parameters are optional, you should use request parameters.
http://mysite.com/controller_name/function_name?page_name=p1&user_name=u1
And in your controller, use $this->input->get('page_name') and $this->input->get('user_name') to get the value and check if the values are empty.

I know this is an old question but the solution I came up with is simple. It goes something like this:
$this->input->get('limit') ? $this->input->get('limit') : 20;

passing a large string through url in codeigniter

how do i pass a large string as a variable in codeigniter? i am trying show the user an article, if the article has more than 800 characters and less than 3044 characters i am showing it in a jquery pop up window, and if the article is more than 3044 charcters i want to pass the article body and title through the url to a controller function.
here is what i have tried:
<?php
if(strlen($home_content[1]['content'])>800 && strlen($home_content[1]['content'])<3044)
{
$substr=substr($home_content[1]['content'],0,786);
echo $substr.'<p id="button"><i>read more...</i></p>';
}
else if(strlen($home_content[1]['content'])<800)
{
echo $home_content[1]['content'];
}
else
{
$substr=substr($home_content[1]['content'],0,786);
echo $substr.'<br/>';
echo anchor('site/read_article/'.$home_content[1]['title'].$home_content[1]['content'],'<i>read more...</i>');
}
?>
and this is the url after passing the data:

and i get this error message:
An Error Was Encountered
The URI you submitted has disallowed characters.
how do i do it correctly? the url looks very messy, how do pass the string and still have a clean url? please help me with it.

Why not pass the article ID instead? You could then access the article through the controller function, count the characters and decide the method of display.
Alternatively, you could use CI's Session Flashdata to pass the article title/body to the next controller and access it that way.
The URI is failing as security is set up to deny specific characters being passed in the URL. This is for your protection, but, although not recommended, could be disabled in the config files if required.
