Error messages when entering data

I have two questions.
1.I have to enter values to database through php. When I enter incorrect value, it gives the error message. But i want to give it as a pop up message. how can i do that?

2. If I enter incorrect value and after the pop up message comes , I want to details that i entered earlier are exist. Otherwise I have to enter all these again. How can i do that?

 

Well, you can get error message using this function:

$errormessage = mysql_error();

PHP:

I suppose you are using MySQL.
Popping it is html/javascript question.

If you want to save data that was entered you have to put values to input fields of form using $_GET or $_POST array.

 

Easy. In the form use:

<form target="_blank">
form stuff
</form>

Then in the target page, you can throw the error off to the user, otherwise close the window.

Another thing toy can do is onclick submit the form to a specific size and get the values using parent get variables.

Peace,

 

well..you can use javascript within php to and use alter to show popup message.....

 

you can use something like that.......

echo "<script>alert('plese enter correct value');</script>";

in a exact postion to use it..
