致命错误:非抽象方法NF_Handlers_FieldsetRepeater::isFieldsetData()必须包含

Question

真的很想帮忙！我试着删除分号，但仍然得到了以下错误：

非抽象方法NF_Handlers_FieldsetRepeater::isFieldsetData()必须在第173行的/home/warstdam/public_html/wp-content/plugins/ninja-forms/includes/Handlers/FieldsetRepeater.php中包含

致命错误

/**
 * Determine if data matches fieldset repeater construct
 *
 * When given only a submission value without any meta data, check the
 * construct of the value to asssert with some level of confidence that
 * the value is from a fieldset repeater.
 *
 * Logic: 
 *  - is submission empty? then NO, we don't assert is fieldset repeater data
 *  - can the array key be parsed as a fieldset repeater key?  If not, then NO…
 *  - is each value an array with 'id' and 'value' keys,
 *    and the `id` matches the id of its parent?  If not, then NO...
 *
 * If all the above conditions are met for every entry in the submission,
 * we assert that the submission value is that of a fieldset repeater.
 * 
 *  
 * @param array $submission
 * @return boolean

public function isFieldsetData(array $submission); bool
{
    $return = true;

    // If not array containing data, not fieldset repeater
    if (empty($submission)) {
        $return = false;
    }

    foreach($submission as $key=>$submissionValueArray){
        $submissionReference = $this->parseFieldsetFieldReference($key);

        if(-1===$submissionReference){
            $return = false;
        }

        if(!isset($submissionValueArray['id'])
           || $key!==$submissionValueArray['id']
           || !isset($submissionValueArray['value'])){
            $return = false;
        }
    }

下面是代码的结尾

{
    $return = [];

    if (!is_array($fieldSubmissionValue)) {
        return $return;
    }

    if(''!==$fieldId and []!== $fieldSettings){

    }else{
        
        $fieldsetLabelLookup = null;
        $fieldsetTypeLookup = null;
    }


    // $completeFieldsetID is in format {fieldsetRepeaterFieldId}{fieldsetDelimiter}{fieldsetFieldId}{submissionIndexDelimiter}{submissionIndex}
    foreach ($fieldSubmissionValue as $completeFieldsetId => $incomingValueArray) {

        // value is expected to be keyed inside incoming value array
        if (isset($incomingValueArray['value'])) {
            $value = $incomingValueArray['value'];
        } else {
            $value = $incomingValueArray;
        }

        // attempt parsing of fielsetField; if any fail, exit as data is corrupt
        $fieldsetWithSubmissionIndex = $this->parseFieldsetFieldReference($completeFieldsetId);

        if (0 == $fieldsetWithSubmissionIndex['fieldsetFieldId']) {

            return $return;
        }

        $parsedSubmissionIds = $this->parseSubmissionIndex($fieldsetWithSubmissionIndex['fieldsetFieldId']);

        if (-1 === $parsedSubmissionIds['submissionIndex']) {
            return $return;
        }

        $fieldsetFieldId = $parsedSubmissionIds['fieldsetFieldId'];


        $submissionIndex = $parsedSubmissionIds['submissionIndex'];

        $idKey = $fieldId . $this->fieldsetDelimiter . $fieldsetFieldId;

        if(is_null($fieldsetTypeLookup)){
            $fieldsetFieldType='';
        }else{
            $fieldsetFieldType = $fieldsetTypeLookup[$idKey];
        }
        
        if(is_null($fieldsetLabelLookup)){
            $fieldsetFieldLabel='';
        }else{
            $fieldsetFieldLabel = $fieldsetLabelLookup[$idKey];
        }


        $array = [];
        $array['value'] = $value;
        $array['type'] = $fieldsetFieldType;
        $array['label'] = $fieldsetFieldLabel;

        $return[$submissionIndex][$fieldsetFieldId] = $array;
    }

    return $return;
}

}

看上去是语法错误。将; bool更改为: bool。

public function isFieldsetData(array $submission): bool
