PHP code for link with text

Question

I was exploring and ran across this post: Grab First Link From A Post, Grab First Blockquote

I would basically like to do the same thing, but have it call not only the URL but also the link, since I am using the link as an excerpt title.

For example; if my link is <a href="http://www.facebook.com/>Facebook</a> I want it to call a link that says Facebook not one that says http://www.facebook.com like the current code does.

This is probably easy when given the code provided already, but I can't figure it out.

Answer 1

maybe try with php DOMDocument rather than regex. I don't think all DOMDocument methods will work with just an html fragment and not a complete document, but for your needs it may be enough:

<?php
$dom= new DOMDocument();
$html = '<p>Some html with a <a href="http://foo.com/">link</a>. Some more text and <a href="http://bar.com/">another</a> link.</p>';
$dom->loadHTML( $html );
$dom->preserveWhiteSpace = false;
$elements = $dom->getElementsByTagName( 'a' );
foreach ( $elements as $element ){
    echo "link text: " . $element->nodeValue . "<br>";
    echo "href value: " . $element->getAttribute( 'href' ) . "<br><br>";
}

// outputs:
//
// link text: link
// href value: http://foo.com/
//
// link text: another
// href value: http://bar.com/

I'm actually trying to do this too.

The following code calls up the link, but not like you're asking (with the actual text for the link included). If you figure this out please post it and let us know, I could really use it!

function get_content_link( $content = false, $echo = false )
{
    // allows using this function also for excerpts
    if ( $content === false )
        $content = get_the_content(); // You could also use $GLOBALS['post']->post_content;

    $content = preg_match_all( '/href\s*=\s*[\"\']([^\"\']+)/', $content, $links );
    $content = $links[1][0];
    $content = make_clickable( $content );

    // if you set the 2nd arg to true, you'll echo the output, else just return for later usage
    if ( $echo === true )
        echo $content;

    return $content;
}

Answer 3

You could build a function that does something like this.

$partnersite = <a href="http://www.facebook.com/>Facebook</a>;
$partnersite = explode('>', $partnersite);
$partnersite = explode('<', $partnersite[1]);
echo $partnersite[0];
