[ballouta]

Hello

I have this form:

 

<FORM name=frm method="POST" action="register.php">
<p dir="ltr" style="margin-bottom: 15px">
<font face="Verdana" color="#FF0000" style="font-size: 9pt; font-style: italic">
required fields</font></p>
<table border="0" width="100%" id="table1" cellspacing="0" cellpadding="0">
	<tr>
		<td width="87"><font face="Verdana" size="2">Full Name</font></td>
		<td width="23">
		<p align="center"><font face="Verdana" size="2">:</font></td>
		<td>
		<input type="text" name="fname" size="20" style="color: #000000"></td>
	</tr>
	<tr>
		<td width="87"><font face="Verdana" size="2">Email</font></td>
		<td width="23">
		<p align="center"><font face="Verdana" size="2">:</font></td>
		<td>
		<input type="text" name="email" size="20" style="color: #000000"></td>
	</tr>
	<tr>
		<td width="87"><font face="Verdana" size="2">Mobile #</font></td>
		<td width="23">
		<p align="center"><font face="Verdana" size="2">:</font></td>
		<td>
		<input type="text" name="mobile" size="20" style="color: #000000"></td>
	</tr>
<tr>
		<td width="87"><font face="Verdana" size="2">Country</font></td>
		<td width="23">
		<p align="center"><font face="Verdana" size="2">:</font></td>
		<td>
		<input type="text" name="country" size="20" style="color: #000000"></td>
	</tr>
	<tr>
		<td width="87"><font face="Verdana" size="2">password</font></td>
		<td width="23">
		<p align="center"><font face="Verdana" size="2">:</font></td>
		<td>
		<input type="password" name="pass" size="20" style="color: #000000"></td>
	</tr>

 

and this javascript in a separate file, it working properly.

 

function isReady() {

// check if the First Name is valid
    if (isProper(frm.fname.value) == false) {
        alert("Please enter your First Name");
        return false;
    }

// check if the email address is valid
    if (isEmail(frm.email.value) == false) {
        alert("Please enter a valid email address");
        return false;
    }
    return true;
}

 

I need to add to code:

1) mobile verification, only numbers are allowed, no matter how long

2) make sure that the password is between 8 and 12 characters.

 

Thanks alot

Add it, let us know how it works.  When you run into trouble, show us.

I don't know how to make the mobile and password check functions.

 

Please help

You will want to look into Regular Expressions for both PHP and Javascript (cannot trust that someone won't turn javascript off in order to circument your filter).  Google it.
