"Is there any way to display a link over an image"? Yes, but it doesn't involve PHP, but HTML and usings stylesheets to move transparent <div>s around. It would be much easier to make the image a link itself, which is plain introductory-level HTML. Then you'd put the text of the link in the image.

"the default error messages generated by PHP contains links also"
Really? I've never seen them.

And instead of just mindlessly pointing people back to older threads, ask yourself why no-one has answered them. Maybe you didn't explain your problem well enough.

thanks for ur reply.....

i think i can explain again what the problem i have.......

this was the class code i hv created to get the error messages

<?php
class _Error_Handler
{
	var $_e_type;
	var $_e_message;
	var $_e_file;
	var $_e_line;

//Constructor
function _Error_Handler()
{
	$this->_set_handler();
}

//Sets the Error Handler
function _set_handler()
{
	set_error_handler(array(&$this,"handler"));
}

//error Handler
function handler($error_type, $error_message,$error_file, $error_line)
{
	switch($error_type)
	{
		case E_ERROR:
			$this->assign_values("Fatal Error",$error_message,$error_file,$error_line);
			break;
		case E_WARNING:
			$this->assign_values("Warning",$error_message,$error_file,$error_line);
			break;
		case E_PARSE:
			$this->assign_values("Parse Error",$error_message,$error_file,$error_line);
			break;
		case E_NOTICE:
			$this->assign_values("Notice",$error_message,$error_file,$error_line);
			break;
		case E_COMPILE_WARNING:
			$this->assign_values("Compile Warning",$error_message,$error_file,$error_line);
			break;
		case E_CORE_ERROR:
			$this->assign_values("Core Error",$error_message,$error_file,$error_line);
			break;
		case E_CORE_WARNING:
			$this->assign_values("Core WARNING",$error_message,$error_file,$error_line);
			break;
		case E_USER_ERROR:
			$this->assign_values("User Error",$error_message,$error_file,$error_line);
			break;
		case E_USER_WARNING:
			$this->assign_values("User Warning",$error_message,$error_file,$error_line);
			break;
		case E_USER_NOTICE:
			$this->assign_values("User Notice",$error_message,$error_file,$error_line);
			break;
		case E_ALL:
			$this->assign_values("All",$error_message,$error_file,$error_line);
			break;
	}
}

// function used to assign values for member variables
function assign_values($_etype,$_emessage,$_efile,$_eline)
{
	$this->_e_type = $_etype;
	$this->_e_message = $_emessage;
	$this->_e_file = $_efile;
	$this->_e_line = $_eline;

	$this->show_error();
}

function show_error()
{
?>

<html>
	<body onload="document.frm_error.submit();">
		<form name="frm_error" action="errorpage.php" method="post">
			<input type="hidden" name="etype" value="<?php echo $this->_e_type;?>">
			<input type="hidden" name="emessage" value="<?php echo urlencode($this->_e_message); ?>">
			<input type="hidden" name="efile" value="<?php echo $this->_e_file;?>">
			<input type="hidden" name="eline" value="<?php echo $this->_e_line;?>">
		</form>
	</body>
</html> 

<?php
	}
}

$eh = new _Error_Handler();
?>

i am using this code to get the values in the errorpage.php

	if (isset($_POST['emessage']))
	{
		$_e_message = htmlspecialchars($_POST['emessage'], ENT_QUOTES);

	$str       = $_e_message;
	$newtext   = wordwrap($str, 45, "/--/");
	$str_array = explode("/--/",$newtext);							
}
else
{
	$_e_message = "";
}

i am getting links in error messages...so i am using urlencode and htmlspecialchars to get the full message with tag.........and i am using GD to display this error message in an image......

i am getting only the text displayed over the image not the link that was created........

now Weedpacket.......tell me is there any possibility to get the text with the link over an image.....

rajavel

if this is not enough means...tell me......i will explain once again.......try to help me....i must use GD to display the error...

GD is for making graphics .. jpg, png and gif stuff. These things cannot contain links. What you're trying to do is impossible with just a graphic. You need to make an html page with the link in it using one script, and the graphic that will be displayed in the page using another.

It'd be much, much simpler just to display the error as text without using GD at all. Why do you need to make it an image exactly?

rajavel

thank u for ur reply onion2k 🙂

i am having full error message page with images sliced by my disigner......the message is to be displayed at the center slice of the page....so i am in need of displaying the message over the image......if i use html instead of image the image sliced part of my page will look ugly....that is the reason why i am trying this......tell me if u hv any other idea.....

Are you using tables or layers? I've found using layers are better for overlays. You can use GD or a src image and have an overlay if you use a layer based layout.
