i am new in PHP
i have a question please
can i run javascript functions which depend on variable that may change in server side ?
for more clarification kindly check the below code
it is a code of form
- Code: Select all
<form method="post" action="insert.php" onSubmit="return insertmsg('<?php echo $confirmation ?>')">
<table dir="rtl" align="center" >
<tr>
<td>Full name</td>
<td> <input type="text" name="name" /> </td>
</tr>
<tr>
<td>address</td>
<td> <input type="text" name="address" /> </td>
</tr>
<tr>
<td>birthdate</td>
<td> <input type="date" name="bdate" /> </td>
</tr>
<tr>
<td>tele</td>
<td> <input type="text" name="tele" /> </td>
</tr>
<tr>
<td>mobile</td>
<td> <input type="text" name="mobile" /> </td>
</tr>
<tr>
<td>image</td>
<td> <input type="text" name="img" /> </td>
</tr>
<tr>
<td colspan="2" style="text-align: center;"> <input type="submit" name="Add" /></td>
</tr>
</table>
</form>
and here code of php inside the same page [ validation before insertion ]
- Code: Select all
<?php
include 'Functions.php';
$name=$_POST['name'];
$add=$_POST['address'];
$bdate=$_POST['bdate'];
$tele=$_POST['tele'];
$mobile=$_POST['mobile'];
$img=$_POST['img'];
$submit=$_POST['Add'];
if($submit)
{
connection();
$length=strlen($tele);
$error=array();
if(!$name)
{
$error[]="Please Enter your name ";
}
elseif((is_numeric($name))||(preg_match('#[0-9]#',$name)))
{
$error[]= "No numbers allowed";
}
if(!$tele)
{
$error[]="please enter your telephone number";
}
elseif ($length!=10)
{
$error[]="telephone number must be 10 digit ! ";
}
$confirmation=0;
$len=sizeof($error);
if($len>0)
{
foreach ($error as $items)
{
echo $items;
echo "</br>";
}
$confirmation=0;
}
else
{
$confirmation=1;
//Function of insert
insertson($name,$add,$bdate,$tele,$mobile,$img) ;
}
}
?>
and finally a Javascript function
- Code: Select all
<script type='text/javascript'>
function insertmsg(var z)
{
if(z==1)
{
var x=confsert these data ? ");
if(x)
{
return true;
}
else
{
return false;
}
}
else
{
return false;
}
}
</script>
All i want is :
customer will insert new data
senario 1 ) ..if he enter correct data , i need to show a confirm box , are u sure ? and then insert the data
senario 2 ) ..if he enter wrong data , validation error appeared and no need to run the java script function
in the above code i think to make a variable [ %confirmation ] and give this value to the JS function
but i also think that Javascript is a client side so it won't see the value of $confirmation witch run on the server ....kindly clarify this point and help me please
Thanks
