[SOLVED] form behaving strange

[vinpkl]

hi all

 

a strange thing is happening

 

i have two fields "new_cutout" and "new_price". they both are defined as float fields in mysql.

 

i m updating their values and also validating them with javascript.

 

If I enter "500.00" in new_cutout field and "0.00" in new_price field and press submit button then both the values of new_cutout field and new_price field changes to "0.00" automatically.

 

not able to know why is the value of new_cutout changing to "0.00" automaticaly.

 

Is the problem of javascript or float.

 

 

<script language="javascript">
function validate()
{
if(document.form1.new_cutout.value='0.00')
{
alert("Enter new cutout price");
return false;
}
if(document.form1.new_price.value='0.00')
{
alert("Enter new price");
return false;
}
}
</script>

<form action="" method="post" enctype="multipart/form-data" name="form1" id="form1" onsubmit="return validate();">
<input type="text" name="new_cutout" id="new_cutout" /> 
<input name="new_price" type="text" id="new_price" /> 
<input type="submit" name="submit" id="submit" value="Modify Product Price" /></td>
</form>

 

<?php
$msg="";
if(isset($_REQUEST['submit']))
{
$new_cutout=$_REQUEST['new_cutout'];
$new_price=$_REQUEST['new_price'];

$qry="update product_table set cutout_price=$new_cutout, price=$new_price where product_id=$id";

if(mysql_query($qry))
{
$msg="Product Price updated successfully";
}
else
$msg="Error updating product Price";
}
?>

hi emopoops

 

on clicking the submit button the validation works and shows the alert "enter cutout price".

 

the page didnt refreshed.

 

the value changes to "0.00" but  i entered 500.00 in that field.

This is more a javascript problem, but

if(document.form1.new_cutout.value='0.00')

 

should be

 

if(document.form1.new_cutout.value=='0.00')

 

you want to use the comparison operator(==) not the assignment operator(=) Whats happening is you are assigning that value of your text box 0.00, and the assignment operator returns true when your assignment assigns to something that is not NULL or false.

oh i see. yeah does the == work?
