Question

I am using Codeigniter framework and I have a form with input fields. When I want to insert the values of inputs fields into database I use this code

function add($tableName)
{
    $fieldsData = $this->db->field_data($tableName); // to get all fields name of the table like (id,title,post .. )
    foreach ($fieldsData as $key => $field)
    {
        $datacc = array(  $field->name => $this->input->post($field->name) ); 
        echo $this->input->post($field->name) ; // when I submit the form I get all that data I need like (mySubjet, MyPost...)
    } // but when I insert the data it insert just the last filed like ( cat_id = 3 ) only !// and the other fields are empty ..
    $this->db->insert($tableName, $datacc);
}

so I get only the last value inserted in the database but when I put the query line inside foreach loop like:

function add($tableName)
{
    $fieldsData = $this->db->field_data($tableName);
    $datacc = "";
    foreach ($fieldsData as $key => $field)
    {
        $datacc = array(  $field->name => $this->input->post($field->name) );
        $this->db->insert($tableName, $datacc); // inside the loop !
    }
}

it insert 15 records / rows (the number of fields in the table) and insert a unique value for every row. Inserts the TITLE field in the first row, the POST field in the next row and dateOfpost field in the third and so on.

You have an array called $datacc, but you are resetting it every time. You need to append to it.

function add($tableName)  
{
    $fieldsData = $this->db->field_data($tableName);
    $datacc = array(); // you were setting this to a string to start with, which is bad
    foreach ($fieldsData as $key => $field)
    {
        $datacc[ $field->name ] = $this->input->post($field->name);
    }
    $this->db->insert($tableName, $datacc);

}

This inserts one row, but builds up the $datacc array as it goes.
