    <p>I am trying to edit a specific cell once it's clicked. When I click a cell currently it turns all the <code>td</code> into textboxes. I would like only the clicked cell do that. How can I access just the clicked cell? Here is my current code: (ignore the <code>.change</code> function for now; I haven't fixed it yet.</p> <pre><code> $(document).ready(function() { $(".edit_td").click(function() { $(this).children(".text").hide(); $(this).children(".editbox").show(); }).change(function() { var id=$(this).parent(); var field=$("#input_"+ id).val(); var text=$("#span_" + id).val(); var dataString = 'id='+ id +'&amp;field='+ field +'&amp;text='+ text; //$("#first_"+ID).html('&lt;img src="load.gif" /&gt;'); // Loading image if(input != text) { $.ajax({ type: "POST", url: "table_edit_ajax.php", data: dataString, cache: false, success: function(html) { $("#first_"+ID).html(first); $("#last_"+ID).html(last); } }); } else { alert('Enter something.'); } }); // Edit input box click action $(".editbox").mouseup(function() { return false }); // Outside click action $(document).mouseup(function() { $(".editbox").hide(); $(".text").show(); }); }); </code></pre> <p>This is my PHP code:</p> <pre><code> public function displayTable($table) { //connect to DB $con = mysqli_connect(DB_HOST, DB_USER, DB_PASS, DB_NAME); echo "&lt;table id='table' border='1'&gt;"; //start an HTML table $dbtable = $table; $fields =array(); $result = mysqli_query($con, "SHOW COLUMNS FROM ".$dbtable); //fill fields array with fields from table in database while ($x = mysqli_fetch_assoc($result)) { $fields[] = $x['Field']; } $fieldsnum = count($fields); //number of fields in array //create table header from dbtable fields foreach ($fields as $f) { echo "&lt;th&gt;".$f."&lt;/th&gt;"; } //create table rows from dbtable rows $result = mysqli_query($con, "SELECT * FROM ".$dbtable); while ($row = mysqli_fetch_array($result)) { $rowid = $row[$fields[0]]; echo "&lt;tr class='edit_tr' id='".$rowid."'&gt;"; foreach ($fields as $f) { echo "&lt;td class='edit_td'&gt;&lt;span id='span_".$rowid."' class='text'&gt;".$row[$f]."&lt;/span&gt; &lt;input type='text' value='".$row[$f]."' class='editbox' id='input_".$rowid."'/&gt; &lt;/td&gt;"; } $rowid++; echo "&lt;/tr&gt;"; } echo "&lt;/table&gt;"; //close the HTML table //close connection mysqli_close($con); } </code></pre>

Guidance
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.
