重命名php select元素的MYSQL列名

Question

Hi I'm constructing a html select element like so:

$result = mysql_query("SHOW COLUMNS FROM table") or die(mysql_error());
    echo '<select name="column" class="column">';
    while ($row = mysql_fetch_array($result))
    {
        if($row[0] == 'id' || $row[0] == 'tstamp' || $row[0] == 'boiler2oil')
              continue;
        echo "<option value='".$row[0]."'>".ucwords($row[0])."</option>";
    }
    echo '</select>';

The way i've named the columns in the table is rather ugly, with underscores, etc...how can i rename them so i can change the select element display (value can stay the same) changes to something a bit more readable and visually pleasing. Is this possible? Would it be some sort of preg_match/preg_replace?

Answer 1

可能仅用str_replace就能完成，对于像这样的简单事情，它比preg_replace更有效。

Answer 2

Depends what you want to rename them to. Do you want to do something simple like remove underscores? Is there a rule you can use to clean them all up?

If not, why not add a hash with entries that map from the name in the table to the name you want to print out for the drop-down list?

# map from column name to display name
$labels = array(
    'col1' => 'Column 1',
    ...
);

$result = mysql_query("SHOW COLUMNS FROM table") or die(mysql_error());
echo '<select name="column" class="column">';
while ($row = mysql_fetch_array($result))
{
    if($row[0] == 'id' || $row[0] == 'tstamp' || $row[0] == 'boiler2oil')
          continue;

    # use a more friendly name if one has been defined above in $labels
    if(array_key_exists($row[0], $labels))
          $label = $labels[$row[0]];
    else
          $label = $row[0];

    echo "<option value='".$row[0]."'>".$label."</option>";
}
echo '</select>';

You can define an array which will be having columnName as "key" and Name to Display as "value". Then Echo element of this array rather than displaying column name.
