Maq Posted May 15, 2009 Share Posted May 15, 2009 If all the fields are checked, and you want to have a button appear, then you need to use JS, this is a client side action where PHP does not exist.

Psycho Posted May 15, 2009 Share Posted May 15, 2009 Do you really need to show/hide a second submit button? Your example code would seem to indicate you only need to change the value of the current submit button. Anyway the code below will show/hide the second submit button: <html> <head> <script type="text/javascript"> function checkFields() { if (document.getElementById('field1').value!='' && document.getElementById('field2').value!='' && document.getElementById('field3').value!='') { document.getElementById('submit2').style.visibility='visible'; } else { document.getElementById('submit2').style.visibility='hidden'; } return; } </script> </head> <body> Field 1: <input type="text" name="field1" id="field1" onkeyup="checkFields();" /><br /> Field 2: <input type="text" name="field2" id="field2" onkeyup="checkFields();" /><br /> Field 3: <input type="text" name="field3" id="field3" onkeyup="checkFields();" /><br /> <input type="submit" name="submit" id="Submit" value="submit" /> <input type="submit" name="submit2" id="Submit" value="1" style="visibility:hidden;" /> </body> </html> Link to comment https://forums.phpfreaks.com/topic/158273-hidden-input/#findComment-834844 Share on other sites More sharing options...

Psycho Posted May 17, 2009 Share Posted May 17, 2009 Once you click submit the page is submitted and will reload. You could have the buttin show as soon as you click submit, but it will only display for a fraction of a second before the page reloads. I think you need to clearly explain what you are trying to accomplish.

ilikephp Posted May 17, 2009 Author Share Posted May 17, 2009 I have a registration form: when I fill in all the fields, I need to click on the send button so all the fields will be checked for validation; if all the fields are correct, the submit button will appear and a new page will be opened when I click on the submit button. I need this submit button to be appeared if there are no errors. I put it as hidden, how to let it be visible? Thx...

Psycho Posted May 17, 2009 Share Posted May 17, 2009 OK, so the first button really isn't a submit button at all! In this situation you don't want to use two "submit" buttons anyway. If you had simply stated your objective in the beginnign we wouldn't have wasted this time. If you want to do JavaScript validation you simply need to create an onsubmit event that will perform the validation and send the form if validation passes and if validation fails halt the fiorm submission and display the errors. You just need to create a javascript function to perform the valiaftion and return true if there are no errors and return false if there are errors. Then in the FORM tab put an onsubmit trigger like this <form name="theform" onsubmit="return validate();"> Link to comment https://forums.phpfreaks.com/topic/158273-hidden-input/#findComment-836023 Share on other sites More sharing options...
