    text
    copied!<p>I have a script in PHP where I need to detect which button was pressed in a HTML page. I have found lots of similar questions asked by other people, but I am having problems.</p> <p>HTML</p> <pre><code>&lt;form method="post" action="kode/kode_newsletter_operation.php" id="newsletter_step3Form"&gt;

2012 [send_date_hour] =&gt; 01 [send_date_min] =&gt; 50 [preview_email] =&gt; [action] =&gt; newsletter_step3 [newsletter_id] =&gt; 1 ) </code></pre> <p>Both buttons are inside the <code>&lt;form&gt;</code> tag but the <code>$_POST</code> array doesn't include any info about them. What am I doing wrong? Do the most recent browsers send no information about the submit button or am I missing something? I have no skills in javascript to develop a workaround for this, I only know PHP.</p> <p>Thanks in advance.</p>

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
