Codeigniter: function return statement not returning - php

Question

I am trying to return a db value using the following function in case of failure the function is supposed to return an error object. I have separated the code block with If/else statement. The if condition satisfies and the if block is executed. But for some reason the return statement in the if block do not execute and the code execution continues to next statement. I tried the two options on both cases the results are same.
First Code
public function is_defined_headtype($head_id)
{
if ($is_defined = $this->ci->account_head_model->is_defined_headtype($head_id))
{
echo "Im here<br>";
return $this->_success($is_defined, ACC_SUCCESS);
}
echo "Im here also";
// General Error Occurred
return $this->_general_error();
}
Second Code
public function is_defined_headtype($head_id)
{
if ($is_defined = $this->ci->account_head_model->is_defined_headtype($head_id))
{
echo "Im here<br>";
return $this->_success($is_defined, ACC_SUCCESS);
}
else
{
echo "Im here also";
// General Error Occurred
return $this->_general_error();
}
}
In both cases I am getting the following output.
Im here
Im here also{"err":1,"code":1,"msg":"Error"}
Calling function definition
public function add_eam($user_id, $eamname, $entityid, $headid, $eamdescription, $eamisfraction, $eampercentage, $eamamount, $affectedheadid)
{
if (/* $eam_id = $this->ci->account_eam_model->insert_eam($user_id, $eamname, $entityid, $headid) */ true)
{
$is_defined = $this->is_defined_headtype(/* $headid */1);
echo json_encode($is_defined);
if($is_defined == 1)
{
echo "Im here";
exit();
if ($entity_id = $this->ci->account_eam_definition_model->insert_eam_definition(/* $user_id */ 1, $eam_id, $eamdescription, $eamisfraction, $eampercentage, $eamamount, $affectedheadid))
{
return $this->_success($eam_id, ACC_ENTITY_ADDED);
}
else
{
return $this->_general_error();
}
}
echo "Im not here";
exit();
return $this->_success($eam_id, ACC_ENTITY_ADDED);
}
// General Error Occurred
return $this->_general_error();
}

Answer 1

hi i think the error is here
you are doing an if statement with only one '=' this is to set a value but you want to comapre so that should be:
'==' to compare that two values are the same
'!=' to see if the two values are different
public function is_defined_headtype($head_id)
{
if ($is_defined = $this->ci->account_head_model->is_defined_headtype($head_id))
{
echo "Im here<br>";
return $this->_success($is_defined, ACC_SUCCESS);
}
echo "Im here also";
// General Error Occurred
return $this->_general_error();
}

In If statement try Type Juggling (int) or use === for strong compare with both side data.
