Hi I´m trying to put an array into option input. But the problem is I get one blank option. I want to remove it.
Here is what I'm trying to do:
<select name "x">
$myarray=array('black','blue','brown');
for ($i=0;$i<=count($myarray);$i++){
if ( $row['colur']==$myarray[$i]) {//if value in database = array$i
echo"<option value='$myarray[$i]' selected>$myarray[$i]</option>";
} else {
echo"<option value='$myarray[$i]'>$myarray[$i]</option>";
}
}
You should loop one item less:
for ($i=0;$i < count($myarray);$i++) {
The last $i your loop "sees" is count($myarray) which is 3 in your case. However, because arrays are zero-indexed, item $myarray[3] doesn't exist (it goes from 0 to 2). The if fails and $myarray[3] is shown, which doesn't exist: you also get an error of level "notice" in your server logs (which should be the trigger to find this all out yourself).
To prevent all this, use foreach:
foreach ($myarray as $color) {
// use $color instead of $myarray[$i]
}
As array index start from 0 to (array length -1), you should mention your for loop accordingly i.e
$array_length = count($myarray);
for ($i=0;$i < $array_length;$i++) {
//your code
}
<select name "x">-><select name="x">. Judging by the fact that you were able to display options at all, I'm guessing that some spaces/characters were lost in the copy/paste process?
