Php in side html drop down selects - php

Question

I'm trying to add results into a html dropdown.
The php works if I take it outside the html form: it shows the results, but I need it inside the form
<form><form method="post" action="selldo.php">
<label><br /><br /><br /><br />What slot do you want to Sell?</label>
<select name="pokeSLOT" id="pokeSLOT" style="width:150px;padding-left:5px;">
<option value=""></option>
<?php
$result = mysql_query("SELECT * FROM user_pokemon
WHERE belongsto='$_SESSION[username]'");
while($row = mysql_fetch_array($result))
{
echo $row['id'] . " " . $row['pokemon'];
echo "<br />";
}
?>
</select><br/><br/>
<label>Price You Would Like For The Pokemon?</label>
<input type="int" name="cost" id="cost" maxlength="30"/><br/><br/>
<button name="submit" type="submit" id="Submit_But">Sell</button>
<p> </p><p> </p>
</form>
When I look in the dropdown menu there is nothing but if it makes the SQL out of the form it posts the results to the page so it works fine I just need it in side the drop down html form
p.s i have the connect ontop of the page

Answer 1

You will need to echo out HTML option elements:
while($row = mysql_fetch_array($result)) {
echo "<option>" . $row['id'] . " " . $row['pokemon'] . "</option>";
}
You will probably want to give the option elements a value so the selected option is passed along properly when the form is submitted.

Answer 2

Did you look at the source this code generates?
You will find that your options are all there but just somewhere in the void, not wrapped by any html tags. You'll see something like:
<form>
<select>
<option></option>
your first option
your second option
your third option
your n'th option
</select>
</form>
But what you really need, for the markup to be correct, is this:
<option>your first option</option>
<option>your second options</option>
And so forth... that should be enough for you to get it right! If not...
echo '<option value="' . $row['id'] . '">' . $row['pokemon'] . '</option>';

Answer 3

You have an SQL-injection hole and a possible XSS security hole:
Correct this by changing the php code to:
<?php
$username = mysql_real_escape_string($_SESSION['username']);
$result = mysql_query("SELECT * FROM user_pokemon
WHERE belongsto = '$username' ");
while($row = mysql_fetch_array($result))
{
$id = htmlentities($row['id']);
$pokemon = htmlentities($row['pokemon']);
echo '<option value = "$id"> $pokemon </option>';
}
?>

Answer 4

You're not creating a select! you need the <option></option> tags for that, not just echo out your results...
<select name="pokeSLOT" id="pokeSLOT" style="width:150px;padding-left:5px;">
<option value=""></option>
<?php
$username = mysql_real_escape_string($_SESSION['username']);
$result = mysql_query("SELECT * FROM user_pokemon WHERE belongsto='$username'");
while($row = mysql_fetch_array($result)) : ?>
<option value="<?php echo htmlentities($row['id']);?>"><?php echo htmlentities($row['pokemon']);?></option>
<?php endwhile;?>
</select>

Answer 5

This should do the trick:
<select name="pokeSLOT" id="pokeSLOT" style="width:150px;padding-left:5px;">
<?php
$result = mysql_query("SELECT * FROM user_pokemon WHERE belongsto = '$_SESSION[username]'");
while($row = mysql_fetch_array($result)) {
echo "<option value=\"\">" . $row['id'] . " " . $row['pokemon'] . "</option>
?>
</select>
