foreach help

[flemingmike]

hello, im submitting a form that has 2 text fields.  im using javascript to add in another 2 fields if needed.  im not sure how to use a foreach to get both field twice.  here is my code below

$myInputsd = $_POST["d"];
$myInputsq = $_POST["q"];
foreach ($myInputsd as $eachInputd) {
foreach ($myInputsq as $eachInputq) {


	 $sql = "INSERT INTO test VALUES (
	 NULL, 
	 $eachInputd,
	 $eachInputq
	 )";
	 mysql_query($sql) or die('Error adding.  Check you fields and try again.');
	 
	 
     echo $eachInputd . $eachInputq . "<br>";
}
}

We'll probably need your full code as to how you are building the text fields and the javascript you're using to make those too.  Usually you don't use foreach loops on text fields but rather checkboxes or radio buttons.  Why are you thinking you need to use a foreach loop on them?  Can you explain your situation in more depth please so we can understand and post the rest of the relevant code.

form:

<script src="addInput.js" language="Javascript" type="text/javascript"></script>
<form method="POST" action="post.php">
     <div id="dynamicInput">
          Entry 1<br><input type='text' name='d[]'> <input type='text' name='q[]'>
     </div>
     <input type="button" value="Add another text input" onClick="addInput('dynamicInput');">
	 <input type="submit" value="Submit" name="submit">
</form>

javascripts:

var counter = 1;
var limit = 6;
function addInput(divName){
     if (counter == limit)  {
          alert("You have reached the limit of adding " + counter + " inputs");
     }
     else {
          var newdiv = document.createElement('div');
          newdiv.innerHTML = "Entry " + (counter + 1) + " <br><input type='text' name='d[]'> <input type='text' name='q[]'>";
          document.getElementById(divName).appendChild(newdiv);
          counter++;
     }
}

Once I get this test working my full version form will have 8 txt boxes for each "Add Another"

if inputs are always in pairs

foreach ($_POST['d'] as $k => $d) {
    $q = $_POST['q'][$k];
    // insert $d and $q into db table
}

So if I wanted to submit it as 3 fields and the third being r, would I do it as below?

foreach ($_POST['d'] as $k => $d) {
    $q = $_POST['q'][$k];
    $r = $_POST['r'][$k];
    // insert $d and $q into db table
}
