    <p>I was wondering how can i set max width and max height before the image is uploaded. So when you click on choose file, you select your picture and it loads up so you can see it. Then you crop it then eventually select upload to save it in a directory now my question is how can i set max width and max height before you get a chance to preview it after you select it in when prompt after selecting choose file.</p> <p>Once You Choose Your File If The Image Is Higher Than The Max Height And Max Width Throw a Message and ask them for a smaller picture</p> <p>HTML CODE:</p> <pre><code>&lt;img id="uploadPreview" style="display:none;"/&gt; &lt;!-- image uploading form --&gt; &lt;form action="upload.php" method="post" enctype="multipart/form-data"&gt; &lt;input id="uploadImage" type="file" accept="image/jpeg" name="image"/&gt; &lt;input type="submit" value="Upload"&gt; &lt;!-- hidden inputs --&gt; &lt;input type="hidden" id="x" name="x" /&gt; &lt;input type="hidden" id="y" name="y" /&gt; &lt;input type="hidden" id="w" name="w" /&gt; &lt;input type="hidden" id="h" name="h" /&gt; &lt;/form&gt; </code></pre> <p>Jquery CODE:</p> <pre><code>function setInfo(i, e) { $('#x').val(e.x1); $('#y').val(e.y1); $('#w').val(e.width); $('#h').val(e.height); } $(document).ready(function() { var p = $("#uploadPreview"); // prepare instant preview $("#uploadImage").change(function(){ // fadeOut or hide preview p.fadeOut(); // prepare HTML5 FileReader var oFReader = new FileReader(); oFReader.readAsDataURL(document.getElementById("uploadImage").files[0]); oFReader.onload = function (oFREvent) { p.attr('src', oFREvent.target.result).fadeIn(); }; }); // implement imgAreaSelect plug in (http://odyniec.net/projects/imgareaselect/) $('img#uploadPreview').imgAreaSelect({ // set crop ratio (optional) aspectRatio: '1:1', onSelectEnd: setInfo }); }); </code></pre>

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.
