(413) Request Entity Too Large error during file upload PHP
<p>I am facing a problem which is related to PHP file upload . I am trying to submit a form using AJAX . This ajax request contains text variables and file(s) . When I am trying to send only one file then everything is going okay but in case I am sending more than one file. I am getting <strong>413 Request Entity Too Large</strong> error . I am using Apache . Here is my code</p>
<pre><code>const data = new FormData();
data.append('name', 'my upload file');

for (const i = 1; i &lt;= 4; i++) {
    const img = $(`#src${i}`).find('img').attr('src');
    data.append(`image${i}`, img || '');
}

$.ajax({
    type: &quot;POST&quot;,
    url: &quot;server.php&quot;,
    data: data,
    cache: false,
    processData: false,
    contentType: false,
    success: (result) =&gt; {
        console.log(1);
    }
});
</code></pre>
<p>All my uploaded files are lesser than 700KB , I also checked the PHP configuration using ini_get_all() and I found that post_max_size is 48MB , upload_max_filesize is 32MB . I am not getting that what is the reason for that problem .</p>
<p>To check that whether I am exceeding the allowed upload limit , I added four files (each with 10KB) but it also generating same problem while I am able to send one file of 400KB . Is there any way to identify the root cause of this problem.</p>
