CronlasthitField

CronlasthitField is a display-only field that reads the cron_last_trigger parameter from the J2Commerce component configuration and renders a Bootstrap alert summarising when the cron system last fired, from which URL, and from which IP address. It stores no user-submitted data — a hidden <input> with an empty value is included solely to satisfy Joomla's form rendering pipeline.

Class Details

Property	Value
Class	CronlasthitField
Namespace	J2Commerce\Component\J2commerce\Administrator\Field
File	administrator/components/com_j2commerce/src/Field/CronlasthitField.php
Extends	Joomla\CMS\Form\FormField
Field type string	Cronlasthit
Since	6.0.7

Behavior

The field reads ComponentHelper::getParams('com_j2commerce')->get('cron_last_trigger', '') and displays one of three states:

State	Alert class	Content
Value is empty	alert-info	Translated COM_J2COMMERCE_CRON_LAST_TRIGGER_NOT_FOUND
Value is valid JSON	alert-success	Formatted COM_J2COMMERCE_CRON_LAST_TRIGGER_DETAILS with date, URL, IP
Value is non-JSON string	alert-info	Raw HTML-escaped value

The JSON payload written by the cron controller has the shape:

{
    "date": "2026-03-04 14:22:01",
    "url": "https://example.com/index.php?...",
    "ip": "203.0.113.42",
    "success": true
}

XML Usage

<form addfieldprefix="J2Commerce\Component\J2commerce\Administrator\Field">
    <fieldset name="cron">
        <field
            name="cron_last_trigger"
            type="Cronlasthit"
            label="COM_J2COMMERCE_CRON_LAST_TRIGGER_LABEL"
        />
    </fieldset>
</form>

XML Attributes

Attribute	Required	Description
name	Yes	Must match the parameter name cron_last_trigger so Joomla binds the correct value from component params.
type	Yes	Must be Cronlasthit.
label	Yes	Language key for the field label.

Output Structure

<div class="alert alert-success mt-n3 mb-0">
    <strong>Last run: 2026-03-04 14:22:01 from https://... (IP: 203.0.113.42)</strong>
</div>
<input type="hidden" name="{field-name}" id="{field-id}" value=""/>

The hidden input always has an empty value — the actual cron_last_trigger parameter is written directly by the cron execution controller, not through this form field.

Usage Notes

• Place this field in the Queues or Cron configuration fieldset so store owners can verify the cron is running.
• The field reads the component parameter directly; it does not use the form's bound data. This means it always reflects the live stored value, even if the form has unsaved edits.
• The success flag in the JSON payload is parsed but not currently used for visual differentiation — all valid JSON results render with alert-success.
