    <p>For some reasons my javascript form validation does not go through every row in the table. I created the table with the codes below: The $usr variable is just a result of another process:</p> <pre><code>&lt;form name="myForm" action="addAccessories.php" method="post" onsubmit="return validateForm(this);"&gt; &lt;table border="1" id="IT"&gt; &lt;tr&gt; &lt;th&gt;Barcode&lt;em&gt;*&lt;/em&gt;&lt;/th&gt; &lt;th&gt;Current stock&lt;/th&gt; &lt;/tr&gt; &lt;?php for($id=1; $id&lt;=$usr; $id++){ ?&gt; &lt;tr&gt; &lt;td&gt;&lt;input type="hidden" name="id[]" value="&lt;?php echo $id; ?&gt;" /&gt; &lt;input type="text" name="bar_code&lt;?php echo $id; ?&gt;" id="bar_code&lt;?php echo $id; ?&gt;" value="" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="num_stock&lt;?php echo $id; ?&gt;" value="0" id="num_stock&lt;?php echo $id; ?&gt;"/&gt;&lt;/td&gt; &lt;?php } ?&gt; &lt;tr&gt; &lt;td&gt; &lt;/td&gt; &lt;td&gt; &lt;button data-theme="b" input type="submit" name="Submit" value="Submit"&gt;Add accessories&lt;/button&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; </code></pre> <p>The number of rows from this table is: rows = $usr + 1</p> <p>My validation form codes:</p> <pre><code>&lt;script type="text/javascript"&gt; function validateForm(){ var errors = []; for(i = 1; i &lt; document.getElementById("IT").rows.length; i++){ var barcode = document.getElementById('bar_code'+i).value; var des = document.getElementById('description'+i).value; var num_stock = document.getElementById('num_stock'+i).value; if(barcode == null || barcode == ""){ errors[errors.length] = "You must enter barcode."; } if(isNaN(num_stock)){ errors[errors.length] = "Current stock must be an integer"; } if(num_stock &lt; 0){ errors[errors.length] = "Current stock must be a positive number"; } if (errors.length &gt; 0) { reportErrors(errors); return false; } return true; } } function reportErrors(errors){ var msg = "There were some problems...\n"; for (var i = 0; i&lt;errors.length; i++) { var numError = i + 1; msg += "\n" + numError + ". " + errors[i]; } alert(msg); } &lt;/script&gt; </code></pre> <p>This process only validates the 1st row in the table then stop. Can anyone show me what went wrong and how to fix it? Thank you very much for your help</p>

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.

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