[SOLVED] trim and then replace

Bloke · 2020-07-26 18:36:09

In the spirit of not repeating yourself, you might have more luck like this:

<txp:variable name="id_num"><txp:yield name="media" /></txp:variable>
<txp:variable name="remote_file">https://cdn.mcstatic.com/contents/videos_screenshots/<txp:variable name="id_num" trim="/(.*)\d{3}/" replace="${1}000" />/<txp:yield name="media" />/830x467/2.jpg</txp:variable>
<txp:php>
$handle = fopen(parse('<txp:variable name="remote_file" />'), 'r');
if ($handle) {
    echo '<img src="<txp:variable name="remote_file" />" width="830" height="467" alt="Testing" />';
}
</txp:php>

Thanks Stef, ~~that works.~~

A last question. Is there a way to expand this in order to check for 3, 4, 5, 6, or 7.jpg if 2.jpg does not exist, and ignore the call if none of them exist?

Unfortunately the suggestion breaks when there is no image in that url

So I am now using the original code I posted but with the variables as Stef suggested.

<txp:variable name="id_num"><txp:yield name="media" /></txp:variable>
<txp:variable name="remote_file">https://cdn.mcstatic.com/contents/videos_screenshots/<txp:variable name="id_num" trim="/(.*)\d{3}/" replace="${1}000" />/<txp:yield name="media" />/830x467/2.jpg</txp:variable>
<txp:php>
$remoteFile = '<txp:variable name="remote_file" />';
$handle = @fopen($remoteFile, 'r');
if(!$handle){
    echo 'Image not found';
}else{
    echo '<img src="<txp:variable name="remote_file" />" />';
}
</txp:php>
<txp:variable name="remote_file" /><txp:hide>temp: checking if the right url is parsed</txp:hide>

The problem is that I am still getting false negatives, ‘‘Image not found” even though the remote_file variable appears ok. Any ideas?

You need to use parse() here, as I did in my original example:

$remoteFile = parse('<txp:variable name="remote_file" />');

Thanks, that indeed, did do it.
