I want to do it with foreach loop. I have tried by following code but it is not show anything except
`print_r($_POST['mech_show']);`.
$all_make_model= $_POST['mech_show'];
$all_make_model_data = $all_make_model['mech_info'];
foreach ($all_make_model_data as $key => $mec_value) {
echo "string";
echo $meta_value['make'];
}
echo "<pre>";
print_r($_POST['mech_show']);
exit();
also not able to go under foreach and data not print in loop.
given me error
Notice: Undefined index: mech_info
Warning: Invalid argument supplied for foreach() in
i also trie this way but
$all_make_model= $_POST['mech_show'];
$all_make_model_data = $_POST['mech_info'];
foreach ($all_make_model as $key => $mec_value) {
echo "<pre>";
print_r($mec_value['make']);
echo "</pre>";
}
echo "<pre>";
print_r($all_make_model['mech_info']);
but it's showing Warning: Illegal string offset 'mech_info' in ..
I don't know if my code is wrong or I'm missing something anyone pls help me.
Thank You

Answer 1

Some change your foreach loop. it $meta_value['make'] should be $mec_value['make']
So,
$all_make_model= $_POST['mech_show'];
//$all_make_model_data = $all_make_model['mech_info'];
foreach ($all_make_model as $key => $mec_value) {
echo "<pre>";
print_r($mec_value['make']);
echo "</pre>";
}

try
$all_array=array("mech_info"=>array("make"=>"Amaka",array("year"=>2001,"model"=>array("one","two","three")),array("year"=>2002,"model"=>array("one","two","three")),array("year"=>2003,"model"=>array("one","two","three")),array("year"=>2004,"model"=>array("one","two","three"))),array("mech_info"=>array("make"=>"PRI",array("year"=>2001,"model"=>array("one","two","three")))));
$all_make_model= $all_array;
//$all_make_model_data = $all_make_model['mech_info'];
//print_r($all_make_model['mech_info']);
foreach ($all_make_model['mech_info'] as $key => $mec_value) {
if(is_numeric($key)) continue;
echo $mec_value; // output Amaka
}
exit();

This Code just work.
To iterate on multiple mech_info, i added a leave in the array, because otherwise you are tring to create multiple object with the same index.
$p = Array('mech_show' => Array(
0 => Array(
'mech_info' => Array(
'make' => 'Amaka',
'0' => Array(
'year' => 2001,
'model' => Array(
0 => 'Test one',
1 => 'test fix',
2 => 'Hamour',
3 => 'Imagica'
)
),
'1' => Array(
'year' => 2002,
'model' => Array(
0 => 'Test Two'
)
),
'2' => Array(
'year' => 2014,
'model' => Array(
0 => 'Test three'
)
),
'3' => Array(
'year' => 2015,
'model' => Array
(
0 => 'test four'
)
)
)
),
1=>Array(
'mech_info' => Array(
'make' => 'PRI',
'0' => Array(
'year' => 2005,
'model' => Array(
0 => 'PRIMODE',
1 => 'Temp Pri',
2 => 'primode',
3 => 'yyy'
)
)
)
)
)
);
$all_make_model= $p['mech_show'];
foreach($all_make_model as $all_make_model_data){
foreach($all_make_model_data as $mech_info)
var_dump($mech_info['make']);
}
where you have to replace $p with $_POST
