Iam newbie to php and codeigniter.
I have error in php,
A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: controllers/search.php
Line Number: 44
Line 44 is: foreach ( $data as $key => $value )
There is some syntax error here, inside this if statement, if (!empty($user['search'])), $data is printed correctly,whereas in this if statement,if(!empty($data)), $data is not printed. Can anyone help me resolve this issue.
The problem is you don't have any value inside your looping variable( $data ).
You can print their values for check whether the variable contains values.
Replace :
$data = json_decode($user['search'])->result;
By :
$data = json_decode($user['search'], true);
json_decode works that way :
var_dump(json_decode($json)); // returns object(stdClass)
var_dump(json_decode($json, true)); returns array
Your $data was an object, while foreach strictly wants an array.
