    <p>I've got a .php registration file that can successfully insert 4 new fields into a user database in my localhost but whenever I add an empty field error check it will stop working. If I don't use an empty field error check all 4 blank values will be added into my user table in localhost. Here's the code in my .php file:</p> <pre><code> &lt;div class="contact"&gt; &lt;div&gt; &lt;h4&gt;Registration Form&lt;/h4&gt; &lt;/div&gt; &lt;div&gt; &lt;table bgcolor="#CCCCCC"&gt; &lt;h4&gt;All fields are necessary and are not to be left empty&lt;/h4&gt; &lt;/br&gt;&lt;/br&gt; &lt;font color="white"&gt;Name&lt;/font&gt;&lt;input class="test1" type="text" id="txNm" value=""&gt; &lt;font color="white"&gt;Username&lt;/font&gt;&lt;input class="test1" type="text" id="txUsn" value=""&gt; &lt;font color="white"&gt;Password&lt;/font&gt;&lt;input class="test1" type="password" id="txPwd" value=""&gt; &lt;font color="white"&gt;E-Mail&lt;/font&gt;&lt;input class="test1" type="text" id="txEml" value=""&gt; &lt;input class="test2" name="Submit" type="submit" value="" id="submit" onClick='submitUser();txNm.value="";txUsn.value="";txPwd.value="";txEml.value="";'/&gt; &lt;/table&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>the submitUser function will then jump over to a js file:</p> <pre><code> function submitUser(){ var name = $('#txNm').val(); var username = $('#txUsn').val(); var password = $('#txPwd').val(); var email = $('#txEml').val(); var finalData = { nm: name, usn: username, pwd: password, eml: email }; $.post('submitUser.php', finalData, function(resp){ if(resp == 'success'){ alert('Thank you for register.'); getUserList(); } }); </code></pre> <p>} then it will jump again go to a submitUser.php file containing the rest of the code here's the contents:</p> <pre><code> $nm = mysql_real_escape_string($_POST["nm"]); $usn = mysql_real_escape_string($_POST["usn"]); $pwd = mysql_real_escape_string($_POST["pwd"]); $eml = mysql_real_escape_string($_POST["eml"]); $q = "INSERT INTO userdb (name, username, password, email) VALUES('$nm','$usn','$pwd','$eml')"; if(!mysql_query($q, $con)){ die('Error: ' . mysql_error()); echo mysql_error(); }else{ echo 'success'; } mysql_close($con); </code></pre> <p>the thing is, everytime I add an empty field error check nothing will happen, if I remove it then the whole registration process will continue but well...even if the fields are all empty.</p> <p>My code is:</p> <pre><code> `if(empty($_POST['txNm'])) { die('You need to enter a value for the Name field'); }` </code></pre> <p>what is wrong with my empty field error check code?</p>

    1. COI think `empty($_POST['txNm'])` should be `empty($_POST['nm'])` because you're passing this as the post data `var finalData = { nm: name, usn: username, pwd: password, eml: email };`

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.
