Printing Array Value

[bam720]

$ModelMFR[] = $_POST['ModelMfr'];
print_r($ModelMFR);

$Fail = PrintOrError($ModelMFR[$i],$Fail);

function PrintOrError($Print,$Fail){
		$Print = stripslashes($Print);
		if($Print == ""){
			echo'<b><font color=red> ERROR </font></b>';
			$Fail++;
		}
		else
			print($Print);
		return $Fail;
	}

outputs:
Array ( [0] => Array ( [0] => Dell [1] => Dell [2] => Dell [3] => Dell ) ) //from print_r

Model Manufacturer: Array //from PrintOrError

My PrintorError works fine with all the other array values just not thsi one. Any ideas?

sorry an example of the html where the post data comes from

  <th scope="row">Model Manufacturer</th>
      <td><center>
          <input name="ModelMfr[0]" type="text" id="ModelMfr" onFocus="if(this.value=='Dell')this.value='';" value="Dell" size="20">
      </center></td>
      <td><center>
          <input name="ModelMfr[1]" type="text" id="ModelMfr" onFocus="if(this.value=='Dell')this.value='';" value="Dell" size="20">
      </center></td>
      <td><center>
          <input name="ModelMfr[2]" type="text" id="ModelMfr" onFocus="if(this.value=='Dell')this.value='';" value="Dell" size="20">
      </center></td>
      <td><center>
          <input name="ModelMfr[3]" type="text" id="ModelMfr" onFocus="if(this.value=='Dell')this.value='';" value="Dell" size="20">
      </center></td>
    </tr>

It's probably because $ModelMFR is a multidimensional array.

I changed my instantiation from

$ModelMFR[] = $_POST['ModelMfr'];

to

$ModelMFR = $_POST['ModelMfr'];

and it works fine now, but i don't understand how it became a multidimensional array when all my other varibles are declared the first way and come out being 1d array's.

When you copy an array into a single element of another array, you end up with a multidimensional array.

Yes I understand that but

$ModelNum[] = $_POST['ModelNum'];

reads all the values from the previous page (see above post with same form elements just named ModelNum) into a 1d array. I am happy that it works now but it bothers me that one is working one way and another is working differently. Thanks

 

[sleipnir214]

This line:

$ModelNum[] = $_POST['ModelNum'];

copies all the elements of $_POST into a single element of the array PHP automatically creates for $ModelNum. The line above is the functional equivalent of saying:

$ModelNum = array()
$ModelNum[0] = $_POST['ModelNum'];

And when you copy an entire array $A into a single element if the array $B, $B then becomes multidimensional.

OK I don't know what I was looking at yesterday. I apologize for the confusion. I tested

print_r($ModelNum);

and the result was this

Array ( [0] => SX270 [1] => SX270 [2] => SX270 [3] => SX270 [4] => Array ( [0] => SX270 [1] => SX270 [2] => SX270 [3] => SX270 ) )

which just means I was getting lucky that the only values i cared about were values at index's 0,1,2,3. I understand what you are saying I just didn't believ you becuase it wasn't happening the same way it was for $ModelMFR. I am now going through and testing each case just to be sure and making the appropriate changes. Thanks fr the help and I apologize for the stubbornness
