I'm using the following script but I cant figure out how to post the form to another php script where I'm trying to email the inputted addresses?

Can anyone point me in the right direction?

Answer 1

Are you setting the action attribute in your form?

<form action="myScript.php">

Answer 2

<form onsubmit="return ValidateForm()" action="another.php" method="post">

Answer 3

if (echeck(str)) {
    submitForm() //or use document.getElementById("formId").submit()
}

Answer 4

On a side note, you may want to look into using regular expressions to validate that email address as opposed to manually looking for specific characters in the string. The code will be more succinct and the expression will capture a wider variety of incorrect entries. You can find a variety of expressions that capture email addresses by doing a quick Google search.
