Question

I am trying to make a program about recipes. The user would have to be able to add more ingredients if he/she wishes to and at the same he can also remove the fields.

I was thinking on what will I name the multiple field and how will I be able to get the values and insert them into the database?

Any help is appreciated. Thanks in advance.

Answer 1

Use square brackets at the end of your field names in HTML and they will appear to PHP as an array:

<input type="text" name="ingredients[]" value="Chicken" />
<input type="text" name="ingredients[]" value="Mushroom" />
<input type="text" name="ingredients[]" value="Cream" />

This will then provide a request variable (let’s assume you use POST for this scenario) so that the request array (i.e. $_POST) appears to PHP (i.e. if you call var_dump) as:

array(1) {
  ["ingredients"]=>
  array(3) {
    [0]=>
    string(7) "Chicken"
    [1]=>
    string(8) "Mushroom"
    [2]=>
    string(5) "Cream"
  }
}
