    <p>I have this and works fine. But can someone tell me is there a SMARTER way to validate this?</p> <p>In the validation here, you may find that the <code>echo "&lt;form.......</code> is replicated thrice to make sure that the form content is also visible along side the validation message when the form is submitted. Im sure there is a more refined method of validating text box content without form being replicated multiple times.</p> <p>Also appreciate if some one can suggest me a method to retain the text box value after the form is being submitted. Usually when the form is submitted the value you enter disappears.</p> <p>Thanks</p> <pre><code>&lt;?php include ("../connection/index.php"); ?&gt; &lt;form method='post' action=''&gt; &lt;input type="submit" name="sendone" id="sendone" value="OneClick"&gt; &lt;/form&gt; &lt;?php if(isset($_POST['sendone'])) { echo "Hello"; echo "&lt;form method='post' action=''&gt;&lt;input type='text' name='txt1' id='txt1'&gt;&lt;input type='submit' name='sendtwo' id='sendtwo' value='TwoClick'&gt;&lt;/form&gt;"; } if(isset($_POST['sendtwo'])) {if($_POST['txt1']=='') { echo "Hello"; echo "&lt;form method='post' action=''&gt;&lt;input type='text' name='txt1' id='txt1'&gt;&lt;input type='submit' name='sendtwo' id='sendtwo' value='TwoClick'&gt;&lt;/form&gt;"; echo "Empty";} else { echo "Hello"; echo "&lt;form method='post' action=''&gt;&lt;input type='text' name='txt1' id='txt1'&gt;&lt;input type='submit' name='sendtwo' id='sendtwo' value='TwoClick'&gt;&lt;/form&gt;"; echo "Hit success!"; }} ?&gt; </code></pre> <p><strong>EDIT</strong></p> <p>Concept</p> <pre><code> &lt;hard coded submit1 button&gt; &lt;dynamically create a text box with a submit2 button&gt; &lt;when submit2 is activated is should validate the text box content&gt; </code></pre> <p>When the validation happens both the vaidated message and the text box should be visible</p>

    1. COAt the top, you could make sure of the following: **1**: All (or at least one of) of your *expected* $_POST variables exist, and **2**: No *unexpected* one's exist. Do that at the top of your script, then you won't need multiple `isset()` calls further down.

    2. COYou could create a session and set each submission values as session values ie. $_SESSION['somevalue']=$_POST['somevalue']; and if it is set, you can echo it out as value <input type="textfield" value="<php echo $_SESSION['somevalue']; ?>"> or something like that

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.
