Hi,

How can I check for a word in a wordpress post?

I would like the code to check for the tags [hidepost] and [/hidepost] and to display a certain text if the tags are found.

How can I do that?

      Not replace, just find. And the find has to take place purely in the code itself, not as a search box.

      To explain it a bit further...


      I would like to know what code can I use to do this:

      Check whether the post content contains the Text "This page has a recommended product."

      And then display a link, For E.g. "www.domain.com" under the post content.

      Is it possible to do something like that?

        I am trying to search for a word in a post. The code has to look through the entire post content to find whether that word exist in it, and to display a text that says so.

        What I am looking to do is:

        Programatically do something like:

        if this condition is true > then perform the following action

        How can this be done?

          Will this shortcode work?

          Code:
          function hidepost_shortcode() {
 
    return '<div align="center"><b>Wait, this is just PART of the secrets revealed... There is MUCH vital information you are missing... <a href="http://www.mindreality.com/view.html">Click Here to View the HIDDEN PART!</a></b></div>';
 
}
add_shortcode('hidepost', 'hidepost_shortcode');
          Or should I be using a filter?

    use pregmatch() to find the text and put condition to what ever you want to do.

      "As a programming overlay, this is twofold: one, you would need a function which calls into the mysql db to "search" the post field for that specific post in the tablespace to see if the word apple exists. Then, you would need a call in the php code itself to call that function which checks the tablespace and then outputs that the term "apple" exists. Makes sense?"

      This was something I thought about at first. Can someone help me with an example of the specific codes I need to use?

    I think this has a search option without having to replace WP – Suchen und Ersetzen (de) (Plugin) | bueltge.de [by:ltge.de]
    I'm not sure if you wanted to search from the site itself or 'behind the scenes'
