PHP loop within a loop, option selected?

问题

Using PHP I echo out table rows in a loop like this:

<?php
/* SQL STUFF */

  while ($row = mysql_fetch_array($select_courseelements)) {
   echo "<tr>\n";
    echo "<td>".$row['scpe_name']."</td>\n";
    echo "<td>".$row['scpe_days']."</td>\n";
   echo "</tr>\n";
  }

Now I would like to include a <select> element with 5 predefined <option> values inside a <td> running with the loop. The option values will be 1 to 5.

There is also a column inside the $row loop that holds a value of 1 to 5 ($row['scpe_grades_status']).

Each time this value is equal to the one in the <select> I want it to change it to selected='selected'.

Would this be possible?

My <select> will look something like this when it's beeing run in the loop:

echo "<td>\n";
echo "<select id='elements_grade'>\n";
        echo "<option value='1'>Registrerad</option>\n";
        echo "<option value='2'>Ej påbörjad</option>\n";
        echo "<option value='3'>Pågående</option>\n";
        echo "<option value='4'>Godkänd</option>\n";
        echo "<option value='5'>Deltagit</option>\n";
        echo "<option value='6'>Ej deltagit</option>\n";
echo "</select>\n";
echo "</td>\n";

回答1:

$array = array('Registrerad' => 1, 'Ej påbörjad' => 2, 'Pågående' => 3, 'Godkänd' => 4, 'Deltagit' => 5, 'Ej deltagit' => 6);

foreach ($array as $key=>$value) {
    if ($value == $row['scpe_grades_status'])
        echo '<option value="'.$value.'" selected>'.$key.'</option>';
    else
        echo '<option value="'.$value.'">'.$key.'</option>';
}

Something like that?

回答2:

Sure, build the values from a loop. and you can compare the values from that part.

for($i = 1; $i<=5; $i++) {
   echo "<option value='$i'";
   echo ($row['scpe_grades_status'] == $i) ? " selected='selected'": "";
   echo ">...."</option>"
}
