selected remain selected

proctk · September 12, 2007

Hi I have the below select box. When the user selects a value I want it to remain selected. It currently changes selected the first value.

any ideas how to do this thanks

<select name="numItems" id="numItems" onchange="this.form.submit()">
  	<option value="21">00</option>
    <option value="20">01</option>
    <option value="19">02</option>
    <option value="18">03</option>
    <option value="17">04</option>
    <option value="16">05</option>
    <option value="15">06</option>
    <option value="14">07</option>
    <option value="13">08</option>
    <option value="12">09</option>
    <option value="11">10</option>
    <option value="10">11</option>
    <option value="09">12</option>
    <option value="08">13</option>
    <option value="07">14</option>
    <option value="06">15</option>
    <option value="05">16</option>
    <option value="04">17</option>
    <option value="03">18</option>

I dont know what method your are trying to use but this is the good example

$selected = ($month == $given )?'selected':'';
$stringMENU  .= "<option value='" .$month. "' ".$selected .">" .$month. "</option>\n\t";

This is what I have but when I select a value the loop never ends it keeps displaying rows and it freezes my browzer

<?php
	$items = $_POST['numItems'];
foreach(array("","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15",
"16","17","18","19","20") as $value)
{
  echo "<option";
  if($value == $items)
  {
    echo " selected='selected'";
  }
  echo ">$value</option>\n";
}
?>
  </select>
   </form>
<?php  
if(isset($_POST['numItems'])){
$numItems = $_POST['numItems'];
}else{

$numItems = 21;
}
while ($numItems <= 20 ) { ?>

thank you for the post, I'm not following what i need to change

teng84 · September 12, 2007

your code declare an array inside the foreach that maybe cause a never ending loop

ant this

if(isset($_POST['numItems'])){

$numItems = $_POST['numItems'];

}else{

$numItems = 21;//<-------------------------------wrong this wont do anything

}

while ($numItems <= 20 ) { ?>

no need for the else just put the code inside that if (all data for this --->>> while ($numItems <= 20 ) { ?>)

should be

if(isset($_POST['numItems'])){
$numItems = $_POST['numItems'];

while ($numItems <= 20 ) { ?>
<dl>
<dt class="floatLeft"><dt><dd class="addPadding"><select name="wholeNum[]">
  <option value="00">00</option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
  <option value="6">6</option>
  <option value="7">7</option>
  <option value="8">8</option>
  <option value="9">0</option>
  <option value="10">10</option>
  </select>
  
  <select name="fraction[]">
  <option value="00">00</option>
  <option value="1/16">1/16</option>
  <option value="1/8">1/8</option>
  <option value="1/4">1/4</option>
  <option value="1/2">1/2</option>
  <option value="3/4">3/4</option>
  
</select>

<select name="meassurement[]" id="measurement">
<option value="">Choose</option>
  <option value="Teaspoon(s)">Teaspoon(s)</option>
  <option value="Tablespoon(s)">Tablespoon(s)</option>
  <option value="Cup(s)">Cup(s)</option>
  <option value="Pint(s)">Pint(s)</option>
  <option value="Quart(s)">Quart(s)</option>
  <option value="Pound(s)">Pound(s)</option>
  <option value="Pintch">Pintch</option>
  <option value="Ounce">Ounce</option>
</select>

<input name="ingredient" type="text" /></dd>
