pull add image href in functions.php

Hey,

Added some code to the functions.php to pull single images from posts into a template and all working great.

With thanks to

Code reads:



function getImage($num) {

global $more;

$more = 1;

$link = get_permalink();

$content = get_the_content();

$count = substr_count($content, '<img');

$start = 0;

for($i=1;$i<=$count;$i++) {

$imgBeg = strpos($content, '<img', $start);

$post = substr($content, $imgBeg);

$imgEnd = strpos($post, '>');

$postOutput = substr($post, 0, $imgEnd+1);

$postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);;

$image[$i] = $postOutput;

$start=$imgBeg+$imgEnd+1;

}

if(stristr($image[$num],'<img')) { echo '<a class="image-post" href="'.$link.'">'.$image[$num]."</a>"; }

$more = 0;

}



// add a favicon for your admin

function admin_favicon() {

	echo '<link rel="Shortcut Icon" type="image/x-icon" href="'.get_bloginfo('template_directory').'/favicon.ico" />';

}

However, I hope a simple question, at the moment its set to added the permalink to the img href, what should be added to link to the single image url?

Many thanks

Rob

This function will grab image URL from first image found in the post using regular expressions:
```
function get_image_from_text($text) {

    $imageurl = "";

    preg_match('/<\s*img [^\>]*src\s*=\s*[\""\']?([^\""\'>]*)/i', $text, $matches);

    $imageurl = $matches[1];

    return $imageurl;

}
```
$matches contains all found images, and function by default returns first one.

Try this code

function getImage($num) {

global $more;

$more = 1;

$link = get_permalink();

$content = get_the_content();

$count = substr_count($content, '<img');

$start = 0;

for($i=1;$i<=$count;$i++) {

$imgBeg = strpos($content, '<img', $start);

$post = substr($content, $imgBeg);

$imgEnd = strpos($post, '>');

$postOutput = substr($post, 0, $imgEnd+1);

$postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);;

$image[$i] = $postOutput;

$start=$imgBeg+$imgEnd+1;

}

if(stristr($image[$num],'<img')) {

preg_match('/src\s*=\s*\"(^\")+/', $image[$num], $m);

$imglink = $m[1];

echo '<a class="image-post" href="'.$imglink.'">'.$image[$num]."</a>";

}

$more = 0;

}



// add a favicon for your admin

function admin_favicon() {

	echo '<link rel="Shortcut Icon" type="image/x-icon" href="'.get_bloginfo('template_directory').'/favicon.ico" />';

}

Please post if there are any errors/problems.

It seems it doesn't return anything inside the href tag.

Replace the preg_match line with this one
```
preg_match('/src\s*=\s*\"([^\"]+)/', $image[$num], $m);
```
