How to Restrict a Specific Word from Post Title

28th Feb 2011 | Posted by reza | 8 Comments

Hooks are very useful in WordPress. They allow you to “hook” custom functions to an existing function, and allow you to modify WordPress’ functionality without editing the core files.

This article shows simple usage of WordPress hook. The hook we are using here is post_publish, to restrict a specific word from post title. You can read more about hook in WordPress here : link


function titlerestriction($title){
	global $post;
	$title = $post->post_title;
	$restrictedWord = "forbidden";
	if (stristr( $title, $restrictedWord)) 
	wp_die( __('Error: This title is containing restricted word') );
}
add_action('publish_post', 'titlerestriction');

Put the code in your function.php. And You can replace word “forbidden” with other word you want to restrict.

Was looking for this, thanks!

I guess we can also use an array of words instead of just one, right?

sure, the code will be like this


function titlerestriction($title){
	global $post;
	$title = $post->post_title;
	$restrictedWords = "forbidden1;forbidden2;forbidden3";
	$restrictedWords = explode(";", $restrictedWords);
	foreach($restrictedWords as $restrictedWord){
		if (stristr( $title, $restrictedWord)) 
		wp_die( __('Error: This title is containing restricted word') );	
	}

}
add_action('publish_post', 'titlerestriction');

the array of restricted words here are forbidden1, forbidden2 and forbidden3
We can add more words but should be separated with “;”
just like the code above

Hello,

I am working on site in wordpress, where all the Jobs are pulled from the external jobs sites, such as monster, indeed, simplyhired. jobs are getting published on site randomly. but I need to explode the jobs titles after specific ascii character ” – ” for ex Sales and Marketing Manager – Mortons Steakhouse – San Francisco, CA and extract last jobs Address from the title and call it in location column.

Can somebody give me php function for this as the ” – ” is common for all jobs titles published on site.
