Attention! You can delete and update several file property values only within a single call, not via several, due to property value IDs are being changed simultaneously. For example:
|
|---|
This method supposes that you collect all values to be deleted for a 1 file property (PROPERTY_VALUE_ID for each file) into an array. Then, deleting is performed.
<?php
$obElement = \CIBlockElement::GetList(
[],
[
'ID' => (int)$aElementID,
'IBLOCK_ID' => (int)$iMainIblockId
],
false,
false,
[
'ID',
'IBLOCK_ID',
]);
if ($obFields = $obElement->GetNextElement()) {
$arProperties = $obFields->GetProperties();
if (!empty($arProperties)) {
/**
* Collect files for deleting into an array,
* group by properties
*/
foreach ($arProperties as $sPropCode => $arPropValues) {
/**
* $sPropCode - property code, searched by us for deleted file without PROPERTY_ and _VALUE, for example PHOTO
* $arPropValues - PROPERTY_VALUE_ID of deleted file
* $arFiles["FILE_DELETE"] - array containing file IDs for all properties to be deleted
* $sValue - searched ID
*/
foreach ($arPropValues['VALUE'] as $iKeyValue => $sValue) {
if (in_array($sValue, $arFiles["FILE_DELETE"]) && $arPropValues['PROPERTY_VALUE_ID'][$iKeyValue] > 0) {
$arDeleteList[$sPropCode][$arPropValues['PROPERTY_VALUE_ID'][$iKeyValue]] = [
'VALUE' => [
'del' => 'Y',
]
];
}
}
}
/**
* When array for files deleting isn't empty
* perform the deleting
*/
if (!empty($arDeleteList)) {
foreach ($arDeleteList as $sPropForDelete => $arDeleteFiles) {
CIBlockElement::SetPropertyValueCode(
$aElementID,
$sPropForDelete,
$arDeleteFiles
);
}
}
}
}

SetPropertyValues
CIBlockElement::SetPropertyValues(
int ELEMENT_ID,
int IBLOCK_ID,
array PROPERTY_VALUES,
string PROPERTY_CODE = false
);
This method saves values of all iblock element properties. Static method.

Call parameters
| Parameter | Description |
|---|---|
| ELEMENT_ID | Element ID with property values to be set. |
| IBLOCK_ID | Information block ID. |
| PROPERTY_VALUES | Array with property values, matching property codes and values.
When PROPERTY_CODE is set, it must contain a single or array with all property values (multiple) for specified element. When PROPERTY_CODE is false, the PROPERTY_VALUES must be an Array("property code1"=>"property value1", ....), where "property code" - numerical or symbolic property code, "property values" - single or array of all property values (multiple). And the array PROPERTY_VALUES must contain a full set of property values for this element, i. e. if one of properties will be missing from it - all property values for this element will be deleted. This is the case for all property types, except for file. Files must be deleted via array with the parameter "del"=>"Y". When the file property type is multiple, the file will be deleted in case if the 'del' parameter is present, independently from its value. Notes:
|
| PROPERTY_CODE | Update property code. When this parameter is different from false, updates only the property with this code. Optional parameter, set as false by default. |
Examples
Example 1:
<?
$ELEMENT_ID = 18; // element code
$PROPERTY_CODE = "PROP1"; // property code
$PROPERTY_VALUE = "Blue"; // property value
// Set new value for this property of this element
$dbr = CIBlockElement::GetList(array(), array("=ID"=>$ELEMENT_ID), false, false, array("ID", "IBLOCK_ID"));
if ($dbr_arr = $dbr->Fetch())
{
$IBLOCK_ID = $dbr_arr["IBLOCK_ID"];
CIBlockElement::SetPropertyValues($ELEMENT_ID, $IBLOCK_ID, $PROPERTY_VALUE, $PROPERTY_CODE);
}
?>
Example 2 (method call code for the "String" property):
$value="text";
CIBlockElement::SetPropertyValueCode("$ELEMENT_ID", "code", $value);
Example 3 (method call for "HTML/text" property):
$value="text";
CIBlockElement::SetPropertyValueCode("$ELEMENT_ID", "code", array("VALUE"=>array("TEXT"=>$value, "TYPE"=>"html")));
Example 4 (adding a description to value):
CIBlockElement::SetPropertyValues ( $PRODUCT_ID, $IBLOCK_ID, array("VALUE"=>$prop_value,"DESCRIPTION"=>$prop_description), $property_name );
Example 5 (deleting "File" property):
CIBlockElement::SetPropertyValuesEx(ELEMENT_ID, IBLOCK_ID, array(PROPERTY_ID => Array ("VALUE" => array("del" => "Y"))));
Example 6:
When a complete product details must be updated, including multiple type values (jointly with description), you can do it using a single Update call. You need to add the description (DESCRIPTION) to values (VALUE) of multiple type properties, write a numerical or symbolic property code (of multiple type) to PROPERTY_VALUES and assign array with value type as follows:
$arrFields = Array(
'PROPERTY_ID_OR_CODE' => Array(
Array(
"VALUE" => 'value1',
"DESCRIPTION" => 'desc for value1'
),
Array(
"VALUE" => 'value2',
"DESCRIPTION" => 'desc for value2'
)
)
);
