[RESOLVED] get selected option in php

jrough

For some reason I am not getting the $selWave value to echo.
thanks,

echo "<td><select name='search_wave' id='search_wave' >;
     echo "<option value=''>Select Wave</option>;
    $selWave=$search_wave==$wave ? "SELECTED": "";
     echo "<option value='0' $wave=0>0</option>;
     echo "<option value='1' $wave=1>1</option>;
     echo "<option value='2' $wave=2>2</option>;
     echo "<option value='3' $wave=3>3</option>;
     echo "<option value='4' $wave=4>4</option>;
     echo "<option value='5' $wave=5>5</option>;
     echo "<option value='6' $wave=6>6</option>;
     echo "<option value='7' $wave=7>7</option>;
     echo "<option value='8' $wave=8>8</option>;
     echo "<option value='9' $wave=9>9</option>; 
echo "</select>\n";
echo  "the wave". $selWave;

Could you tell us what you're hoping to do with $selWave? Also, please remember to surround your PHP with the

 codes.

For one, you've got a syntax error (noted by the crazy color coding now that I've added the [noparse]

..

[/noparse] bbcode tags around your code).

Second, why on earth do you have so many echo statements (e.g. instead of just one or maybe two)?

Third, where are $search_wave and $wave ever defined? Have you tried echo'ing (or, even better, [man]var_dump/man'ing them) to verify that they hold the values that you think to do?

Finally, what is the point of code like this:

$wave=0

etc. ? Doesn't seem like it's going to result in valid HTML (and, as such, do anything meaningful).

$search_wave is the post value in the search box. but what I really want to do is keep the value selected if the page gets redrawn. but I don't need this line because the value $searcdh_wave is in the post.
$selWave=$search_wave==$wave ? "SELECTED": ""; In any case I think I am making it too complicated.

<?php
//for testing
//$_POST['search_wave']='2'; 
echo "<td><select name='search_wave' id='search_wave' >;
    <option value=''>Select Wave</option>";
for($i = 0 ; $i<10 ; $i++){

echo '<option value="'.$i.'"';
if($_POST['search_wave']==$i){
	echo ' selected="selected" ';
}
echo '>'.$i.'</option>';
}
echo "</select>\n";
if(!empty($_POST['search_wave'])){
	echo "the wave".$_POST['search_wave'];
}

?>
