HTML every 5 iterations on foreach - php

Question

I´m using extra_user_details.php on wordpress to show user details in a private profile page. As I´m using a lot of extra fields I though about break the query and make the same output every X values in order to show as tabs:
function eud_extract_ExtraFields() {
if ( get_option( 'eud_fields' ) ) {
$all_fields = unserialize( get_option( 'eud_fields' ) );
if ( count( $all_fields ) > 0 ) {
$output = '';
foreach ( $all_fields as $key => $value ) {
if ( isset($value[3]) && ! empty($value[3]) ) {
if ( ($value[3] == 'disable') || ! current_user_can($value[3]) ) {
continue;
}
}
$output .= '<tr>
<th><label for="eud' . esc_attr( $value[1] ) . '">' . esc_attr( $value[0] ) . '</label></th>
<td><input name="eud' . esc_attr( $value[1] ) . '" id="eud' . esc_attr( $value[1] ) . '" type="text" value="' . esc_attr( get_user_meta( get_user_id(), $value[1], true ) ) . '" class="regular-text code" /> <span class="description">' . ( ( isset( $value[2] ) && $value[2] !== '' ) ? esc_attr( stripslashes( $value[2] ) ) : '' ) . '</span></td>
</tr>';
}
}
if ($output != '') {
echo '<div><table class="form-table">';
echo $output;
echo '</table></div>';
}
} }
Thanks!
I´m not sure if this is what I´m looking for. I´m just near...
function eud_extract_ExtraFields() {
if ( get_option( 'eud_fields' ) ) {
$all_fields = unserialize( get_option( 'eud_fields' ) );
if ( count( $all_fields ) > 0 ) {
$output = '';
$i=0;
foreach ($all_fields as $key => $value ) {
if ( isset($value[3]) && ! empty($value[3]) ) {
if ( ($value[3] == 'disable') || ! current_user_can($value[3]) ) {
continue;
}
}
$output .= '<tr>
<th><label for="eud' . esc_attr( $value[1] ) . '">' . esc_attr( $value[0] ) . '</label></th>
<td><input name="eud' . esc_attr( $value[1] ) . '" id="eud' . esc_attr( $value[1] ) . '" type="text" value="' . esc_attr( get_user_meta( get_user_id(), $value[1], true ) ) . '" class="regular-text code" /> <span class="description">' . ( ( isset( $value[2] ) && $value[2] !== '' ) ? esc_attr( stripslashes( $value[2] ) ) : '' ) . '</span></td>
</tr>';
++$i;
if(!($i % 2)) {
echo '<div><table class="form-table">';
echo $output;
echo '</table></div>';
}
}
}
}
}
But I need to split the echo, I mean, now the results are:
first tab echo 1, 2
second tab echo 1,2,3,4
third tab echo 1,2,3,4,5,6
and I need the $output to be just:
first tab echo 1,2
second tab echo 3,4
third tab echo 5,6
fourth tab echo 7 (if exists)

Answer 1

You could use modulus:
$i=0;
foreach ( $all_fields as $key => $value ) {
if( $i++%5 === 0 ){ echo 'I was number 5';}
}
or if you prefer a binary comparison (should be faster):
if( $i++&101 === 0 ){ echo 'I was number 5';}
I'll give you an example, you can piece it together for your code:
Lets say you have an N amount of span, and you want them grouped per 5 in a div:
// You start with:
echo '<div>';
for($i=1; $i<=23; $i++){
echo '<span> '.$i.' </span>'; // just an example, could be anything here
}
echo '</div>';
This will place 23 span in one big div. Now we add something to group them by 5:
// You start with:
echo '<div>';
for($i=1; $i<=23; $i++){
echo '<span> '.$i.' </span>'; // just an example, could be anything here
if( $i %5===0 ){
echo '</div><div>'; // every 5th, close the div, and open a fresh one.
}
}
echo '</div>';
This will result in 5 (=coincedence, nothing to do with %5) div's, 4 with 5 spans, and one with the remaining 3. You can do this trick with about any element.
Tip: in the modulus-if-statement you should add the max: $i %5===0 && $i!==23, to prevent </div></div><div> if $i is a number devidable by 5.

Solution came from a friend, thanks!
function eud_extract_ExtraFields() {
if (get_option('eud_fields')) {
$all_fields = unserialize(get_option('eud_fields'));
if (count($all_fields) > 0) {
$output = '';
$i = 1;
$htmlTotal = '';
foreach ($all_fields as $key => $value) {
if (isset($value[3]) && !empty($value[3])) {
if (($value[3] == 'disable') || !current_user_can($value[3])) {
continue;
}
}
$output .= '<tr>
<th><label for="eud' . esc_attr($value[1]) . '">' . esc_attr($value[0]) . '</label></th>
<td><input name="eud' . esc_attr($value[1]) . '" id="eud' . esc_attr($value[1]) . '" type="text" value="' . esc_attr(get_user_meta(get_user_id(), $value[1], true)) . '" class="regular-text code" /> <span class="description">' . ( ( isset($value[2]) && $value[2] !== '' ) ? esc_attr(stripslashes($value[2])) : '' ) . '</span></td>
</tr>';
$i++;
/* number of fields to show per tab */
if ($i % 2) {
$htmlTotal .= '<div><table class="form-table">' . $output . '</table></div>';
$output = '';
}
}
echo $htmlTotal;
}
}
}
