    <p>So I've got this code for a drag and drog file uploader to PHP via ajax, but apparently my web host doesn't have ajax. Is there any way I can do it without ajax? Specifically I am referring to the UploadFile function, towards the end, after the progress bar parts (which don't seem to work either... )</p> <pre><code>(function() { // getElementById function $id(id) { return document.getElementById(id); } // output information function Output(msg) { var m = $id("messages"); m.innerHTML = msg + m.innerHTML; } // file drag hover function FileDragHover(e) { e.stopPropagation(); e.preventDefault(); e.target.className = (e.type == "dragover" ? "hover" : ""); } // file selection function FileSelectHandler(e) { // cancel event and hover styling FileDragHover(e); // fetch FileList object var files = e.target.files || e.dataTransfer.files; // process all File objects for (var i = 0, f; f = files[i]; i++) { ParseFile(f); UploadFile(f); } } //upload images function UploadFile(file) { var xhr = new XMLHttpRequest(); if ( xhr.upload &amp;&amp; file.type == "image/jpeg" || file.type == "image/gif" || file.type == "image/jpg" || file.type == "image/png" &amp;&amp; file.size &lt;= $id("MAX_FILE_SIZE").value ) { //create progress bar var o = $id("progress"); var progress = o.appendChild(document.createElement("p")); progress.appendChild(document.createTextNode("upload " + file.name)); //progress bar xhr.upload.addEventListener("progress", function(e) { var pc = parseInt(100 - (e.loaded / e.total * 100)); progress.style.backgroundPosition = pc + "% 0"; }, true); //file received/failed xhr.onreadystatechange = function(e) { if (xhr.readyState == 4) { progress.className = (xhr.status == 200 ? "success" : "failure"); } }; //start upload xhr.open("POST", $is("upload").action, true); xhr.setRequestHeader("X_FILENAME", file.name); xhr.setRequestHeader("Content-type", file.type); xhr.send(file); } } // initialize function Init() { var fileselect = $id("fileselect"), filedrag = $id("filedrag"), submitbutton = $id("submitbutton"); // file select fileselect.addEventListener("change", FileSelectHandler, false); // is XHR2 available? var xhr = new XMLHttpRequest(); if (xhr.upload) { // file drop filedrag.addEventListener("dragover", FileDragHover, false); filedrag.addEventListener("dragleave", FileDragHover, false); filedrag.addEventListener("drop", FileSelectHandler, false); filedrag.style.display = "block"; // remove submit button submitbutton.style.display = "block"; } } // output file information function ParseFile(file) { Output( "&lt;p&gt;File information: &lt;strong&gt;" + file.name + "&lt;/strong&gt; type: &lt;strong&gt;" + file.type + "&lt;/strong&gt; size: &lt;strong&gt;" + file.size + "&lt;/strong&gt; bytes&lt;/p&gt;" ); // display an image if (file.type.indexOf("image") == 0) { var reader = new FileReader(); reader.onload = function(e) { Output( "&lt;p&gt;&lt;strong&gt;" + file.name + ":&lt;/strong&gt;&lt;br /&gt;" + '&lt;img src="' + e.target.result + '" /&gt;&lt;/p&gt;' ); } reader.readAsDataURL(file); $("#fileselect").val(file); } // display text if (file.type.indexOf("text") == 0) { var reader = new FileReader(); reader.onload = function(e) { Output( "&lt;p&gt;&lt;strong&gt;" + file.name + ":&lt;/strong&gt;&lt;/p&gt;&lt;pre&gt;" + e.target.result.replace(/&lt;/g, "&amp;lt;").replace(/&gt;/g, "&amp;gt;") + "&lt;/pre&gt;" ); } reader.readAsText(file); } } // call initialization file if (window.File &amp;&amp; window.FileList &amp;&amp; window.FileReader) { Init(); } })(); </code></pre>

    2. COAJAX is implemented by you, not supported by your host. If you've got PHP and JavaScript - and you do - you've got all the tools you need. You probably have an error in your code. Consider jQuery, it has great tools to make AJAX easier to implement cross-browser.

    3. COAs was said above, AJAX is client-side technology. Your server needs to be able to dish out JSON (which it can using PHP, alternatives include ASP, PERL, etc)... The rest is completely client-side. It simply makes no sense for you to NOT have AJAX, but have PHP.

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.

SQuiL has stopped working due to an internal error.

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