    <p>I am practicing with PHP and AJAX but I have some problems!</p> <p>I'm trying to get the filename, type, size from a jQuery alert after select an image to upload, but I keep getting an empty string.</p> <pre><code>&lt;form action="upload_file.php" method="post" enctype="multipart/form-data"&gt; &lt;label for="file"&gt;Filename:&lt;/label&gt; &lt;input type="file" name="my_file" /&gt; &lt;input type="submit" name="submit" value="Submit" /&gt; &lt;/form&gt; </code></pre> <p>This form includes a <strong>JS</strong> file that has an ajax script that asks to a php page the filename of the posted file, but it doesn't work. Do I need to upload the file before I try to get this data?</p> <p>The JS file:</p> <pre><code>$("input").change (function () { $.post("preview_uploader.php", { action:"get_size" }, function (data) { alert (data); }); }); </code></pre> <p>The PHP file <strong>preview_uploader.php</strong>:</p> <pre><code>&lt;?php if ($_POST["action"] == "get_test") print "text string test works!"; if ($_POST["action"] == "get_name") print $_FILES["my_file"]["name"]; if ($_POST["action"] == "get_size") print $_FILES["my_file"]["size"]; if ($_POST["action"] == "get_type") print $_FILES["my_file"]["type"]; ?&gt; </code></pre> <p>It works if i make a test with <code>action:"get_test"</code> with php page but it doesn't work with <code>$_FILES["my_file"]["name"]</code> or <code>$_FILES["my_file"]["type"]</code> etc...</p> <p>Can someone help me find where I am wrong?</p> <p>Thanks!</p>

    1. COI tried improving the grammar and making this question clearer, but the sentence structure was odd. Don't know if I got everything correct.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
