 }else{

unset job_category field to readonly}


Thanks

Hi,
use JavaScript to change field on the fly.

Here is a sample:

{literal}<script>

document.forms.editform.value_employment_approved.onchange=function()

{

if(document.forms.editform.value_employment_approved.value=='Yes')

document.forms.editform.value_job_category.disabled=true;

else

document.forms.editform.value_job_category.disabled=false;

}

</script>{/literal}


To add JavaScript code turn on HTML mode on the Visual Editor tab.

hi, Jane

I have similar question:
how to disable rest of the form fileds if selected value is YES?

and where exactly to add this lines of sample code (literals/javascripts)you recommended?Please
my idea is to have 3 or more fields disabled unless YES for one of the forms had been chosen.
thank you again.

Hi,
To add JavaScript code turn on HTML mode on the Visual Editor tab. You can add this code at the end of page.
Here is just a sample:

{literal}<script>

document.forms.editform.value_employment_approved.onchange=function()

{

if(document.forms.editform.value_employment_approved.value=='Yes')

{

document.forms.editform.value_fieldname1.disabled=true;

document.forms.editform.value_fieldname2.disabled=true;

document.forms.editform.value_fieldname3.disabled=true;

}

else

{

document.forms.editform.value_fieldname1.disabled=false;

document.forms.editform.value_fieldname2.disabled=false;

document.forms.editform.value_fieldname3.disabled=false;

}

}

</script>{/literal}

Do you have an example of doing this in php using smarty rather than javascript?

No. PHP is executed on the server, JavaScript is executed on the client side.

Understand that, but if, before the page is displayed I want to change that field to read only (i.e. have it just as a display element rather than a field), is there a way to tell smarty to do this in the event before the page is displayed?
