Replace ShortCode using PHP
Here we have a data.html file with two shortcodes marked by square brackets: [myimage.jpg] and [myimage2.jpg] …
I want to write PHP code to search and replace with these…
<a href=”myimage.jpg”><img src=”myimage.jpg”></a>
<a href=”myimage2.jpg”><img src=”myimage2.jpg”></a>
Shortcodes are like shortcuts that saves me from typing in those long HTML tags. WordPress uses shortcode for certain widgets replacements.
Here is the PHP that I use …
I read the file using PHP’s file_get_contents() into a string $inFile and $outText.
Use preg_match_all on $outText with regular expression “/\[(.*?)\]” to find all shortcodes within brackets. The preg_match_all returns all matches in two arrays. The first array (in our case $matches) is an array of matches with the brackets included. The second array ($mathes) is an array of matches with just the match content (excluding the bracket symbols).
We loop through this second array for all the matched contents. For each matched content (in our case “$match”), we build up a new string in $newValue.
We use str_replace to replace our match with our new string.
And output back to same file using file_put_contents.
