Alert box

[zed420]

Hi ALL

Can anyone tell me how can I use alert error messages without wiping out all the information that user has put in. eg.  I have a form if user makes mistake inserting his/her password an error messages pop up (alert box) but it wipes out rest of the form too. Is there any way I can keep rest of the inserted information.

Thanks

Zed

<input type="text" name="username" value="<?php echo $_POST['username']; ?>" >

Add this to your form

onsubmit="return loginCheck(this)"

 

you can change the below to what you need.

change username to what you want it to check.  the name of the input.

This will run when the submit button is hit.

 

function loginCheck() {
var username = document.login.username;

    if (username.value.length < 1) {
    alert("Enter a User Name.");
    return false;
    }
    else
{
if (username.value.length > 25)
{
alert("Enter a User Name up to 25 characters.");
return false;
}
}
