removing a tag

Hey Ray

If I wanted to remove the styling soemthing like this: 

how would I modify

<?php
function convertString($string) {
    $retStr = $string;
    $retStr = str_replace(array("<br />","<br>","<p>","</p>","<h1>","</h1>","<h2>","</h2>","<blockquote>","</blockquote>","<strong>","</strong>","<em>","</em>","<u>","</u>","&nbsp;"), "", $retStr);
    $retStr = preg_replace("/\<a(.*)\>(.*)\<\/a\>/iU", "$2", $retStr);
		$retStr = preg_replace("/\<span(.*)\>(.*)\<\/span\>/iU", "$2", $retStr);
		$retStr = preg_replace("/\<u(.*)\>(.*)\<\/u\>/iU", "$2", $retStr);
		$retStr = preg_replace("/\<h1(.*)\>(.*)\<\/h1\>/iU", "$2", $retStr);
		$retStr = preg_replace("/\<strong(.*)\>(.*)\<\/strong\>/iU", "$2", $retStr);
    $retStr = preg_replace("/<img[^>]+\>/i", " ", $retStr);
		$retStr = preg_replace("/<h1[^>]+\>/i", " ", $retStr);
		$retStr = preg_replace("/<h2[^>]+\>/i", " ", $retStr);
		$retStr = preg_replace("/<h3[^>]+\>/i", " ", $retStr);
		$retStr = preg_replace("/<p[^>]+\>/i", " ", $retStr);
    return $retStr;
}
?>

As you can see I have $retStr = preg_replace("/\<strong(.*)\>(.*)\<\/strong\>/iU", "$2", $retStr); but it isnt removing the the tag

cheers

The issue is that you are removing the "" tag above in the str_replace, so the preg_replace() won't work because it depends on both the open and close tags to be found before it removes them.

You could try moving the str_replace() to the end like:

php:

<?php

function convertString($string) {

    $retStr = $string;

    $retStr = preg_replace("/\<a(.*)\>(.*)\<\/a\>/iU", "$2", $retStr);

        $retStr = preg_replace("/\<span(.*)\>(.*)\<\/span\>/iU", "$2", $retStr);

        $retStr = preg_replace("/\<u(.*)\>(.*)\<\/u\>/iU", "$2", $retStr);

        $retStr = preg_replace("/\<h1(.*)\>(.*)\<\/h1\>/iU", "$2", $retStr);

        $retStr = preg_replace("/\<strong(.*)\>(.*)\<\/strong\>/iU", "$2", $retStr);

    $retStr = preg_replace("/<img[^>]+\>/i", " ", $retStr);

        $retStr = preg_replace("/<h1[^>]+\>/i", " ", $retStr);

        $retStr = preg_replace("/<h2[^>]+\>/i", " ", $retStr);

        $retStr = preg_replace("/<h3[^>]+\>/i", " ", $retStr);

        $retStr = preg_replace("/<p[^>]+\>/i", " ", $retStr);

    $retStr = str_replace(array("<br />","<br>","<p>","</p>","<h1>","</h1>","<h2>","</h2>","<blockquote>","</blockquote>","<strong>","</strong>","<em>","</em>","<u>","</u>","&nbsp;"), "", $retStr);

    return $retStr;

}

?>

That may work, but I'd suggest using the built in php function strip_tags() instead of this one.

I've seen that you can exclude some tags from the strip_tags function (eg $content=strip_tags($content," <ul><li><ol>");) but unsure how to incorporate that into <?php echo strip_tags($Noticeboard->getColumnVal("NoticeboardContent")); ?>

I am am wanting to strip all tags except <a href>....

2/11/2016 11:47 am | #5 Ray BorduinWebAssist

<?php echo strip_tags($Noticeboard->getColumnVal("NoticeboardContent"),"<a>"); ?>

2/12/2016 4:35 am | #6 Jamie

brilliant thanks...and am assuming that if you wanted other tags to be excluded you just add them with a comma separting? eg ("NoticeboardContent"),"<a>"," "); ?>

2/12/2016 12:36 pm | #7 Ray BorduinWebAssist

It looks like you add them right together without commas like "<a> "
