Add Yes/No Form to Variations Module to globally set "VARIANT_ALLOW_STOCK_MOVEMENT_ON_VARIANT_PARENT" variable - concerns Issue #26965

[DaBootO]

Feature Request

In Issue #26965 the missing check for the Variable "VARIANT_ALLOW_STOCK_MOVEMENT_ON_VARIANT_PARENT" was discussed and fixed in the PR #26967

Now I propose a change in the Variants module settings page to allow the user to set this global variable. This would also be the first and only way to set this variable via an option.

Use case

When a user activates the variations module and checks the possible options inside the module the user will be able to see that there is a possibility to allow the stock movements for the variant parent products as well.

Suggested implementation

Use the same syntax as with the "HideProductCombinations":

dolibarr/htdocs/variants/admin/admin.php

Lines 75 to 76 in e4536e0

	print '<tr class="oddeven"><td>'.$langs->trans('HideProductCombinations').'</td><td>';
	print $form->selectyesno("PRODUIT_ATTRIBUTES_HIDECHILD", getDolGlobalString('PRODUIT_ATTRIBUTES_HIDECHILD'), 1).'</td></tr>';

Generally add a form with a yes/no option to the options page

$form->selectyesno()

Together with a similar syntax as in the Lines 40-56 one could implement and set the variable globally:

dolibarr/htdocs/variants/admin/admin.php

Lines 40 to 56 in e4536e0

	if ($action) {
	$value = GETPOST('PRODUIT_ATTRIBUTES_HIDECHILD');
	if (!dolibarr_set_const($db, 'PRODUIT_ATTRIBUTES_HIDECHILD', $value, 'chaine', 0, '', $conf->entity)) {
	setEventMessages($langs->trans('CoreErrorMessage'), null, 'errors');
	$error++;
	}
	if (!dolibarr_set_const($db, 'PRODUIT_ATTRIBUTES_SEPARATOR', GETPOST('PRODUIT_ATTRIBUTES_SEPARATOR'), 'chaine', 0, '', $conf->entity)) {
	setEventMessages($langs->trans('CoreErrorMessage'), null, 'errors');
	$error++;
	}
	if (!$error) {
	setEventMessages($langs->trans('RecordSaved'), null, 'mesgs');
	}
	}

Suggested steps

• add Option to variants/admin/admin.php via $form->selectyesno()
• add translationkey for new option to langs/en_US
