Question

I’ve got a problem in my foreach saying “Invalid argument supplied for foreach in line …”

This is the code I’m working on:

    protected function jsGenerateResourcesAutocomplete(){
    $employeeNames = $this->employeeNames;
    $html = "";
    $html .= '<script>' . PHP_EOL;
    $html .= 'var employeeNames = [' . PHP_EOL;
    foreach( $employeeNames as $employeeName ){
        $html .= '"' . $employeeName->getEmployeeName() . '",' . PHP_EOL;
    }
    $html .= '];' . PHP_EOL;
    $html .= '$(function() {' . PHP_EOL;
    $html .= '$(#resource-input input:text").each(function() {' . PHP_EOL;
    $html .= '$(this).autocomplete({source: employeeNames});' . PHP_EOL;
    $html .= '})' . PHP_EOL;
    $html .= '})' . PHP_EOL;
    $html .= '</script>' . PHP_EOL;
    return $html;
}

In this line: foreach( $employeeNames as $employeeName ){ throws the error. What is wrong with this?

Answer 1

Firstly please check $employeeNames this is array or not using

  is_array($employeeNames)

then execute foreach loop
