Building an image tag using an image from a diffrent site

ghurty · June 12, 2007

I am trying to edit a code so that images that are placed using a wysiwyg editor (live linked) would display, as of now only images residing on your server that are are displayed.

What would I change so that it could assemble the tag from anywhere, not only from my site ($mosConfig_live_site)?

Thanks

// assemble the <image> tag
		$image = '<img src="'. $mosConfig_live_site .'/images/stories/'. $attrib[0] .'"';

[pre]<img src="http://www.externalsite.com/image.png"> alt="" />[/pre]

Like that?

ghurty · June 12, 2007

I tried to replace it with this:

$image = '<img src="'. $attrib[0] .'"';

But that didnt work.

Here is a copy of the rest of the code from the script if that helps:

	function replaceImage( &$row, $maxchars, $showimage, $width = -1, $height = -1 ) {
	global $database, $_MAMBOTS, $current_charset;

	// expression to search for
	$regex = '/<img\s*.*?>/i';

	$image = $showimage?processImage ( $row, $width, $height ):"";
	$row->introtext = trim($row->introtext);
	$row->introtext = preg_replace( $regex, '', $row->introtext );

	$row->introtext1 = strip_tags($row->introtext);
	if ($maxchars && strlen ($row->introtext) > $maxchars) {
		$row->introtext1 = substr ($row->introtext1, 0, $maxchars) . "...";
	}
	// clean up globals
	return $image;
}

function processImage ( &$row, $width, $height ) {
	global $mosConfig_absolute_path, $mosConfig_live_site;

	// split on \n the images fields into an array
	$row->images 	= explode( "\n", $row->images );
	$img = trim( $row->images[0] );

	// split on pipe the attributes of the image
	if ( $img ) {
		$attrib = explode( '|', trim( $img ) );
		// $attrib[0] image name and path from /images/stories

		// $attrib[1] alignment
		if ( !isset($attrib[1]) || !$attrib[1] ) {
			$attrib[1] = '';
		}

		// $attrib[2] alt & title
		if ( !isset($attrib[2]) || !$attrib[2] ) {
			$attrib[2] = 'Image';
		} else {
			$attrib[2] = htmlspecialchars( $attrib[2] );
		}

		// $attrib[3] border
		if ( !isset($attrib[3]) || !$attrib[3] ) {
			$attrib[3] = 0;
		}

		$attrib[4]	= '';
		$border 	= 0;

		// $attrib[5] caption position
		if ( !isset($attrib[5]) || !$attrib[5] ) {
			$attrib[5] = '';
		}

		// $attrib[6] caption alignment
		if ( !isset($attrib[6]) || !$attrib[6] ) {
			$attrib[6] = '';
		}

		// image size attibutes

		// assemble the <image> tag
		$image = '<img src="'. $mosConfig_live_site .'/images/stories/'. $attrib[0] .'"';

		// no aligment variable - if caption detected
		if ( !$attrib[4] ) {
			$image .= $attrib[1] ? ' align="'. $attrib[1] .'"' : '';
		}
		$image .=' alt="'. $attrib[2] .'" title="'. $attrib[2] .'" border="'. $border .'" '. (($width != -1) ? 'width="'. $width . '"' : '') .(($height != -1) ? ' height="'. $height .'"' : '').' />';

		$img = $image;
	}
	return $img;
}

Oops my post completely screwed.

<img src="http://www.externalsite.com/image.png" alt="" border="0" />

ghurty · June 12, 2007

Oops my post completely screwed.
<img src="http://www.externalsite.com/image.png" alt="" border="0" />

But I cant do that, because the image link is dynamic, depending on what image someone links in the post using wysiwyg editor

chigley · June 12, 2007

Post more code please? Lost.

ghurty · June 12, 2007

Here is the entire code, but I think only the first part effects the image:

As of now it only displays an image that is tagged using {mosimage} (and those have to reside on my server) what I am trying to do is allow it to using a image from a different server.

Thanks
