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"> |

The main problem I see is your use of 'getElementsByName'. That function returns an array and your code isn't written to handle arrays. You should use 'getElementById' instead. Each element in the <form> should have both an 'id' and a 'name' attribute. The 'id' can be used by Javascript and the 'name' can be used by PHP.
As for errors, Javascript errors can be seen using your browsers 'Web Development Tools' or whatever your browser calls it. PHP errors can be found in the php error log, which by default should be in your tmp directory. If you want to see the errors on the page you are working on then put these 2 lines of code, in a php block, at the top of the web document. CODE ini_set('display_errors', 'On'); error_reporting(E_ALL); |
