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"> |

Hello Charles.
Yes, I use POST. The PHP script is written like this: ++++++++++++++++++++++ $conn = new mysqli(...); $sql = "INSERT INTO ... VALUES ('" . $_POST["Name"] . "', '" ... );" $conn->query($sql); ++++++++++++++++++++++ I can put this script also into the HTML form page code if it is more difficult with a php file. But as I said: Main condition is that the fields are validated by attribute 'required' !! I assume that such a solution should exist! If this regardless isn't possible I begin to ask myself why this attribute is existing. My process (saving the form data to a database afterwards) is really a standard one!! I also expected that if a page is been submitted that the form elements are resetted. However, to reset them manually wouldn't be a problem. |
