Loop through an array on form input?

[Solarpitch]

Hey Guys,

 

I have an input array that I need to loop through on form submission then write to the database. Using Codeigniter.. The below inputs child age and month are dynamic so there can be 10 generated by javascript if required.. below we have 2...

 

HTML..

				<h5>Age of Children</h5>

				<input type="text" name="child[att][age]" value="" size="50" />

				<select name="child[att][month]">
				<option value="Jan">Jan</option>
				<option value="Feb">Feb</option>
				<option value="Mar">Mar</option>
				</select>

				<input type="text" name="child[att][age]" value="" size="50" />

				<select name="child[att][month]">
				<option value="Jan">Jan</option>
				<option value="Feb">Feb</option>
				<option value="Mar">Mar</option>
				</select>

 

Then I'm just trying to loop through and save...

 

		foreach($_POST['child']['att'] as $key => $val) {

			// print_r($_POST['child']['att']); -> THIS PRINTS: Array ( [age] => Array ( [0] => 5 [1] => 4 ) [month] => Array ( [0] => Feb [1] => Jan ) ) 



				$insert = array(
				   'entry_id' => $last_id_inserted,
				   'age_of_child' => $val['age'],
                                            'child_month' => $val['month'],
			  	   'date_created' => date('Y-m-d H:i:s'),
			       'last_modified' => date('Y-m-d H:i:s')
             	  );
             	 
          	  
			$this->competition_model->add_entry_children($insert);
		}

 

 

I cant get the values into the variables. So you can see I need to make two DB inserts foreach of the child age and child month thats submitted.

As stated above, print_r($_POST['child']['att']); -> THIS PRINTS: Array ( [age] => Array ( [0] => 5 [1] => 4 ) [month] => Array ( [0] => Feb [1] => Jan ) )

 

Any help appriciated.

As print_r clearly points out, $_POST['child']['att']['age'] & $_POST['child']['att']['month'] are both still arrays. You need to loop through those arrays as well.

Umm.. If I try this..

 

		foreach($_POST['child']['att'] as $key => $val) {

			foreach($_POST['child']['att']['age'] as $key => $val){
				echo print_r($_POST['child']['att']['month']);

			}

			//print_r($_POST['child']['att']);

			exit;

				$insert = array(
				   'entry_id' => $last_id_inserted,
				   'age_of_child' => $val['age'],
			  	   'date_created' => date('Y-m-d H:i:s'),
			       'last_modified' => date('Y-m-d H:i:s')
             	  );
             	 
          	  
			$this->competition_model->add_entry_children($insert);
		}

 

the out put is..

 

Array ( [0] => Feb [1] => Jan ) 1Array ( [0] => Feb [1] => Jan ) 1

You already define $key and $val in your outer loop. You'll need to use different variables within the inner loop.

Ah right Thorpe I see.. So would this be best practice...

 

		foreach($_POST['child']['att'] as $key => $val) {

			foreach($_POST['child']['att']['age'] as $key_1 => $val_1){

			foreach($_POST['child']['att']['month'] as $key_2 => $val_2){


			//print_r($_POST['child']['att']);

				$insert = array(
				   'entry_id' => $last_id_inserted,
				   'age_of_child' => $val_1,
				   'birth_month' => $val_2,
			  	   'date_created' => date('Y-m-d H:i:s'),
			       'last_modified' => date('Y-m-d H:i:s')
             	  );
             	 
          	 
			$this->competition_model->add_entry_children($insert);


			}
		    }	
		}
