    Problems with matching on last element in array

    Hi folks,

    As part of an app I am validating and repopulating user input from
    check boxes. $responses is posted checkbox input, $answers is the
    data used to create and recreate the checkboxes.

    I am having the darned time figuring out why this works for every
    single box in every single group of boxes EXCEPT for the last one.
    Given that it does this persistently across sets of data I know I have
    an error in my logic buy I can't find it.

    I have dumped the data as I iterate over it and it is always exactly
    what I expect.

    Here is print_r() for each array:

    // Here is $answers
    Array
    (
    [0] =Construction
    [1] =Healthcare
    [2] =Cultural Economy
    [3] =Manufacturing
    [4] =Transportation
    [5] =Oil and Gas

    )

    // Here is $responses
    Array
    (
    [0] =Construction
    [1] =Healthcare
    [2] =Cultural Economy
    [3] =Manufacturing
    [4] =Transportation
    [5] =Oil and Gas
    )

    // I have both methods I have used here:

    // METHOD 1
    foreach ($answers as $a) {
    $iter++;
    if ($responses) {
    $ckd = (in_array($a, $responses)) ? 'checked' : '';
    }
    echo " <input type='checkbox' name='answer_" . $iter . "_$this->id'
    id='answer_" . $iter . "_$this->id' value='$a' $ckd onClick='setBox es
    $this->id()'$a<br />\n";
    }


    // so when in_array didn't work I also tried this with the same
    results
    // METHOD 2
    foreach ($answers as $a) {
    $iter++;
    if ($responses) {
    $ckd = '';
    foreach ($responses as $r) {
    if ($r == $a) {
    $ckd = 'checked';
    break;
    }
    }
    }echo "$a is a; $ckd is ckd<br>";
    echo " <input type='checkbox' name='answer_" . $iter . "_$this->id'
    id='answer_" . $iter . "_$this->id' value='$a' $ckd onClick='setBox es
    $this->id()'$a<br />\n";
    }

    Any thoughts?

    TIA!

          Hi Jerry,

          Thanks for the reply!

          $iter = 0 initially.

          Here is an example: http://www.novacvideo.org/registration/form.php?id=2

          Checkbox output code looks like this:

          <input type='checkbox' name='answer_1_ 99' id='answer_1_99 '
          value='Construc tion'checked onClick='setBox es99()'Construc tion<br />
          <input type='checkbox' name='answer_2_ 99' id='answer_2_99 '
          value='Healthca re'checked onClick='setBox es99()'Healthca re<br />
          <input type='checkbox' name='answer_3_ 99' id='answer_3_99 '
          value='Cultural Economy'checked onClick='setBox es99()'Cultural
          Economy<br />

          <input type='checkbox' name='answer_4_ 99' id='answer_4_99 '
          value='Manufact uring'checked onClick='setBox es99()'Manufact uring<br /
          >
          <input type='checkbox' name='answer_5_ 99' id='answer_5_99 '
          value='Transpor tation'checked onClick='setBox es99()'>
          Transportation< br />
          <input type='checkbox' name='answer_6_ 99' id='answer_6_99 ' value='Oil
          and Gas' onClick='setBox es99()'Oil and Gas

          Thanks for your help!

              Arg! I found the error! There was a newline character in the
              database! It was throwing everything in both test datasets!

              Thanks Jerry, I had to look at the output to see it!
