How do I add a dropdown list of numbers 1 - 1000 as an extra profile field?
题
I don't want to write out something like this from 1 to 1000:
<select name="number_pick" id="number_pick" >
<option value="1" <?php selected( '1', get_the_author_meta( 'number', $user->ID ) ); ?>>1</option>
<option value="2" <?php selected( '2', get_the_author_meta( 'number', $user->ID ) ); ?>>2</option>
<option value="3" <?php selected( '3', get_the_author_meta( 'number', $user->ID ) ); ?>>3</option>
</select>
So instead, I am trying to use a foreach statement to get from 1 to 1000. I think I am close, but I have something wrong and I don't know what it is.
<select name="number_pick" id="number_pick" >
<?php foreach (range(0,1000) as $number)
echo "<option value='$number' selected( '$number', get_the_author_meta( 'number_pick', $user->ID ) ) >$number</option>"; ?>
</select>
Can anyone tell me what I am missing in the lines above?
Here is the complete code:
<?php
add_action( 'show_user_profile', 'show_extra_profile_fields' );
add_action( 'edit_user_profile', 'show_extra_profile_fields' );
function show_extra_profile_fields( $user ) { ?>
<h3>Extra profile information</h3>
<table class="form-table">
<tr>
<th><label for="number_pick">Pick A Number</label></th>
<td>
<select name="number_pick" id="number_pick" >
<?php foreach (range(0,1000) as $number)
echo "<option value='$number' selected( '$number', get_the_author_meta( 'number_pick', $user->ID ) ) >$number</option>"; ?>
</select>
</td>
</tr>
</table>
<?php }
add_action( 'personal_options_update', 'save_extra_profile_fields' );
add_action( 'edit_user_profile_update', 'save_extra_profile_fields' );
function save_extra_profile_fields( $user_id ) {
if ( !current_user_can( 'edit_user', $user_id ) )
return false;
update_usermeta( $user_id, 'number_pick', $_POST['gender'] );
}
?>
