PHP+Javascript

[Anon]

Hi,
I would like to adopt Javascript in my Form using PHP to validate the Form, but it does not work.
Can somebody help me please ???

Thank you,
Helen

<SCRIPT LANGUAGE="JavaScript">
//Function called - upon submission of form.\
<!--
function checkForm(form) {

//check name
if (form.name.value == "") {
alert ("Please enter your name");
return false;
}
-->
</SCRIPT>

<?
/ echo (
"\n<SCRIPT language='javascript'>\n" .
"<!-- \n" .
"function checkForm(form) { \n" .
"if (form.name.value == '') { \n" .
"alert (\"Please enter your name\")\n" .
"return false;\n" .
"} \n" .
"// --> \n" .
"<SCRIPT>\n"
);
/

echo "<form onSubmit=\"return checkForm(this)\" method=\"post\" action=\"\">";
echo "<table>";
echo "<tr>";
echo "<td>Name &nbsp;&nbsp; </td>";
echo "<td><input type=\"text\" name=\"name\" size=\"30\"></td>";
echo "</table>";
echo "<input type=\"submit\" value=\"Submit\">";
echo "</form>";
?>

<?
echo $name
?>

Shouldn't you put a else return true in somewhere?

And; why are you first creating the script directly in html, and afterwards creating the same script in php? Or am I missing the big picture here ;-)

Hmm, I only see one actual &lt;form&gt; tag, but maybe I'm missing something. However, one that that certainly is missing is the form action: you're in effect asking to submit the form nowhere...

Someone ones told me if you omit "action" the form submits to itself. Not sure if that's the idea Helen had though.. So that could be related to the problem if you don't expect it ;-)

submits to itself

Wow! You learn something new every day...

Looks to me like you forgot to close your function. There may be some other little syntax errors as well. Your code should read something like:

<script language = "javascript">
function checkForm(form){
if(form.name.value ==""){
alert('Please enter your name');
return false;

} //close the if
} //close the function
</script>

or in PHP--
<?
/ echo (
"\n<SCRIPT language='javascript'>\n" .
"<!-- \n" .
"function checkForm(form) { \n" .
"if (form.name.value == '') { \n" .
"alert (\"Please enter your name\");\n" .
"return false;\n" .
"} \n" .
"} \n" .
"// --> \n" .
"</SCRIPT>\n"
);
/

Hope this helps

Hi all,

Thanks a lot for your help !!
It's true that I've forgotten to close the function. And if the form doesn't have "action" means that the form will submit to it self. ;-))
