Add String to the Field Dynamically

[SIERRA]

Hi,

1. We have 'Seminar_Schedule' repeater field in the template (One of the Admin Control Panel Page)
2. Inside the 'Seminar_Schedule' repeater field, we have 'preview_sms_content' field and other fields.

In this 'preview_sms_content' field (textarea) -

• How to add our SMS Content to this field dynamically. (Based on the values entered on the other input fields)
• How to display the characters count of SMS Content to this field dynamically.
• How to restrict to enter the characters manually.(How to make this field readonly)

PFA and Suggest,

Thank you

Hi,

Could someone please reply?

If this content is not editable you could use FieldtypeCache (a core module) and FieldtypeRuntimeOnly. Create a FieldtypeCache field “sms” and select the fields you would like to combine under the “Details” tab. Create a FieldtypeRuntimeOnly field “preview_sms_content” (instead of your textarea) and edit the associated php file to have something like:

if(empty($page->sms)) {
	return "No content yet";
} else {
	$sms = implode(" ", $page->sms);
	return "$sms (" . strlen($sms) . " characters)";
}

Add both fields to your repeater, save and you should see the SMS preview.

Edit: actually you could skip the FieldtypeCache and just concatenate your strings in the FieldtypeRuntimeOnly php file...
