How to pass data from one page to another in php

Question

I am trying to pass an id from a button in page1 to a variable that's in php in page2. The id is dynamic because there will be multiple buttons and i only need to send the clicked button id. The problem is I don't know where to start really. Do I need to use cookies? I have read some people use sessions but that is a bit overkill I think.

This is the button in page1

<td class="button-table">
     <button class="leads-more-info-btn" 
     id="<?php echo $leadKey = $allIssues->key ?>" 
     onclick="sendData(this.id)">Apply..
     </button>
</td>

As you can see i tried using the onclick, but that is in javascript. I would like to do it in php. And the variable name in Page2 is called $currentLead. So to summarize page1:buttonID->page2:$currentLead.

You can use a link instead of a button, and put a $_GET variable in the url with the id value — entoniperez, Oct 21 '20 at 12:50

You can definitely use $_SESSION as has been mentioned, but I'm fairly sure that you could also refactor your page so that your buttons are either contained in a <form>, or use AJAX to do a $.get() or $.post() to the other page's URL when the button is clicked. You could then check $_GET or $_POST to find/retrieve the values in that page.

A hyperlink to the new page (instead of a button) would work as well. You could simply pass the id in the querystring at that point, and could even style the hyperlinks to look like buttons with CSS if you want to keep the look/feel of a button.

There are some good ideas here, but just be careful storing things in the session - the session is supposed to persist so only save stuff in it you need to persist. I.e. if you need the id only on that page and then not again (e.g. viewing a profile rather than loading a user) then the query string parameter may be a better choice – imposterSyndrome Oct 21 '20 at 14:11
Yay, I can post comments now! Anyway, I agree with @jameson2012 and would not personally use the session option for this. – bdean531 Oct 21 '20 at 14:42

Store it in a $_SESSION, Then use header() function if you want to get redirected to page2
