Hello,
I have a form page where I check the mandatory inputs client-sided by the attribute 'required' (when clicking send button). When all required inputs are done the send button click... 1.) should call a php file 'dbinsert.php' which just contains the save process of the form data to a database. 2.) But the success message should be shown on the SAME page, on top of the form page. How can I implement this process under those 2 conditions? I suppose that the send button's 'action' attrbute should be empty and the php file has to be called via Ajax (within a Javascript function?) !? But unfortunately I fail in implementing THIS specific configuration. Could you help me, please? If so, please specify in your answer all necessary code lines like the form header, the submit button and the Javascript function that executes the Ajax call (and also fires the success message, I suppose)? Thank you so much! The following constellation does not work: * <FORM NAME="Betrugseingabe" ACTION="../cgi-bin/DBinsert.php" METHOD=POST> * <INPUT TYPE="submit" NAME="Absenden" VALUE="Absenden" ID="Schaltflaeche1" formtarget="_self"> |

If you want to make sure your required fields are not blank before you submit the form then all you have to do is click the Submit button. The browser will alert you if any fields are blank. If any fields are blank then the form will not submit.
Also, 'onSubmit' isn't a valid form attribute, well it is a valid event. Get rid of it. The action attribute is where you need to place the path and script name of the PHP script to process the submit. How exactly do you want the form to behave once the submit is clicked?
