    copied!<p>I have a simple Javascript validation code that works fine if I send it to a certain PHP address, while it doesn't work if I send it to a PHP page I have created.</p> <p>The code is quite basic at the moment and validates some fields with regexes.</p> <p>Basically, if I try it with a given ready-made PHP file (I can't access) it works fine presenting me the error dialog box until all the fields are correct.</p> <p>Meanwhile, in the PHP page I made, it catches the error, display the dialog box but on the OK alert box click, it submits the fields to my PHP file.</p> <p>Can someone give me a clue of what's going on?</p> <p>Thank you.</p> <p><strong>This is the Javascript:</strong></p> <pre><code>&lt;script type="text/javascript"&gt; /* &lt;![CDATA[ */ // this function calls all the other functions that validate each field of the submitting form function validate() { var validated = false; validated = validateRId() &amp;&amp; validateEId(); return validated; } // this validates the RID: checking that the field is filled with a number between 1 //and 99999 function validateRId() { var RIdElement = document.getElementById("RID"); patternRId = /^([1-9][0-9]{0,4})$/; if (patternRId.test(RIdElement.value)) { return true; } else { alert ("Please Enter your RID (a number range 1 to 99999))"); RIdElement.focus(); return false } } // this validates the EventID: checking that the field is filled with a number between 1 and 99999 function validateEId() { var EIdElement = document.getElementById("EID"); patternEId = /^([1-9][0-9]{0,4})$/; if (patternEId.test(EIdElement.value)) { return true; } else { alert ("Please Enter the EID (a number range 1 to 99999))"); EIdElement.focus(); return false } } /* ]]&gt; */ &lt;/script&gt; &lt;p/&gt; &lt;form action="http://adress.php" method="post" name="submitrunnertime" onsubmit = "return validate()"&gt; &lt;table&gt; &lt;tr&gt;&lt;td&gt;Runner ID*&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="RID" id="RID" size="5" maxlength="5"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt;&lt;td&gt;Event ID*&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="EID" id="EID" size="5" maxlength="5"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;input type="submit" name="submit" value="submit"/&gt; &lt;hr/&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p><strong>This is the PHP:</strong></p> <pre><code>&lt;body&gt; &lt;?php // access details as variables $username = "xxxx"; $password = "tttt"; $hostname = "rrrrr"; //connection $connection = mysql_connect($hostname, $username, $password) or die ('connection problem:' . mysql_error()); echo $connection .
