// get the faq category
$data['category'] = $this->faq_model->get_category();
// echo "<script>alert('adadsdsa')</script>";
$this->load->view('faq/display_faq_not_approved', $data);
}
I have for-loop for FAQ where display all the FAQ values and I have FAQ category, but in separate table.
I want to display the FAQ category. above I use the nested for-loop but end with an error.
I want to display the nested for loop with in the for-loop for displaying all the category. how to achieve this

Answer 1

Are you using
<?php foreach ($faq as $faq): ?>
Try using some other key, like
<?php foreach ($faq as $f): ?>

Answer 2

Wrong use, keys and values ​​can not be the same.
<?php foreach ($faq as $faq): ?>
<?php foreach ($category as $category){ ?>
for example,
$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
$value = $value * 2;
}

Answer 3

Try
foreach ($faq as $intKey=>$strValue)
so $strValue is the elements as you want
