Question

is_array($src2->crit) is generating an “Undefined property: stdClass::$crit” error.

The line throwing the error is:
if(is_array($src2->crit) && count($src->crit) > 0){

$src2->crit is initialized here.

$src2->crit = array();
 $src2->crit[0] = new dataSet();
 $src2->crit[0]->tblName = $tbl2;
 $src2->crit[0]->colName = "ID";
 $src2->crit[0]->val = $elm->editID;

When testing $src2->crit with this code.

print("\$src->crit is a ".$src->crit."<br />");
print_r($src->crit); print("<br />");

This is returned.

$src2->crit is a Array
Array ( [0] => dataSet Object ( [tblName] => sExam [colName] => ID [val] => 10 ) )

What am I not seeing/understanding correctly? If print("\$src2->crit is a ".$src->crit."<br />") returns that it is an array then why is is_array($src2->$crit) generating an error?

Answer 1

Can’t reproduce:

<?php
$src2 = new stdClass();
$src2->crit = array();
$src2->crit[0] = new stdClass();
$src2->crit[0]->tblName = "whatever";
$src2->crit[0]->colName = "ID";
$src2->crit[0]->val = "value";
var_dump(is_array($src2->crit));

gives bool(true).
