processing form objects thru links and not buttons

kay

hi there! i terribly need help. how can i process form objects, such as check boxes/text fields, through href tags/links and NOT THRU submit buttons? That is, when the user clicks on a link, the value of the selected check boxes/value in the text boxes can be passed and can be retrieved outside the form. many thanks!!!

You want to POST the form when a user clicks on a link? Then here is a solution. It´s not PHP but JavaScript... Try to learn the difference between client side and server side. You will then find that development is easy ;-)

<a href="javascript:document.forms['FORM_NAME'].submit();">Submit form</a>

Hmm... Do not know why there becomes a space between java and script. The right way is with NO space (javascript).

Happy Coding

thanks andrin! the code worked perfectly well. however, would it be possible to pass other variables other than the form objects?

for instance:
the code you gave me was:

  <a href="javascript:document.forms['FROM_NAME].submit();">submit form</a>

  the thing is, i would like to pass other variables in the link. 

  (the structure that is:)  
 <a href="trial.php?var1=kay&var2=andrin">submit</a>

would it be alright if i combine both (javascript and variable passing) in a single link? thanks a lot!!! 🙂

use <input type=hidden name=varname value=desiredvalue> in your form.
Also if the value is a string with a space in it you need to have quotes around the vlaue itself.

thanks! it helped a lot! 🙂 but i have another problem... there are two links in the form and a textbox. the first link increments the value of the textbox by 5 while the other link decrements it by 2. how would i know which link did the user click for me to output right answers? thanks!!!

instead of the earlier suggestion of the other person of making the href the JS form submission make the link a JS function and pass a number to the function so you can make your change then use the above mentioned form submission in the function after your adjustment.
