    <p>In your form check if it is not sending empty values.</p> <p><strong>STEP 1</strong> copy and paste the following code in your text editor and run it. It will allow you to test the values from the form without redirecting the page.</p> <p>The following code should be in index.php</p> <pre><code>&lt;form action="action.php" method="POST" onsubmit="return validate()"&gt; &lt;p&gt;Your name: &lt;input type="text" name="name" id="name"/&gt;&lt;/p&gt; &lt;p&gt;Your age: &lt;input type="text" name="age" id="age"/&gt;&lt;/p&gt; &lt;p&gt;&lt;input type="submit" /&gt;&lt;/p&gt; &lt;/form&gt; &lt;script type="text/javascript"&gt; function validate(){ var name=document.getElementById("name").value; var age=document.getElementById("age").value; alert ("Name="+name+" age="+age); return false; } &lt;/script&gt; </code></pre> <p>This code will check if the values are getting entered correctly without redirecting the page to action.php. </p> <p><strong>Step 2</strong> If you are getting the desired output from the previous code then you can replace the validate function with the code below. (<em>replace everything between the script tags</em>)</p> <pre><code> function validate(){ var name=document.getElementById("name").value; var age=document.getElementById("age").value; if (name==null || name==""){ return false; } if (age==null || age==""){ return false; } return true; } </code></pre> <p>If both name and age are filled in the form, the submit will now redirect to action.php</p> <p><strong>Step 3</strong> In action.php use the following code.</p> <pre><code>&lt;? //These code goes in action.php extract ($_POST); echo "Hi $name. You are $age years old"; ?&gt; </code></pre> <p><em>edited with instructions on OP's request</em></p>

    2. COinclude the first javascript and test the form. If you outputs are getting displayed correctly then replace it with the second one. And yes both goes in index.php. The first function will alert you with the output without redirecting the page and the second function is the actual validation of your form.

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.
