Display repeated fields

Hello, I’ve been trying to display the repeated data into a table but couldn’t find any example on your youtube channel or here, maybe I missed something.

I have the data in an array
```
$array = array(
	get_post_meta( get_the_ID(), 'data1', true ),
 	get_post_meta( get_the_ID(), 'data2', true  ),
 	get_post_meta( get_the_ID(), 'data3', true  ),
);
```
and I’m trying to put it into a table:
```
echo '<table class="table-group">';
foreach ( $array as $row ) {
	echo('<tr>');
	echo('<td>');
	echo( implode( '</td><td>', $row ) );
	echo('</td>');
	echo('</tr>');
}
echo '</table>';
```
The table works, it shows the data but not in the order I want.. it puts all the results of data1…data3 in a column instead of a row. The problem is I’m not sure how I can select the first entry in the array to correspond with the second array’s first entry and so forth. I hope it makes sense?

If this is all wrong kindly refer to me how I would be able to display repeated fields data in a table. Thank you again.

Hello, I managed to get this working but with code you may not agree with because I think it’s really inefficient..

So I realized that the meta key for repeated fields start with an empty key ” ” and then an increment of “_row-1” “_row-2” etc.. with that in mind I came up with this:

$array = array(
	get_post_meta( get_the_ID(), 'data1', true ),
	get_post_meta( get_the_ID(), 'data2', true  ),
	get_post_meta( get_the_ID(), 'data3', true  ),
);

echo '<table class="table-group">';

//the following shows the first group
echo('<tr>');
echo('<td>');
echo $array[0][''];
echo('</td>');
echo('<td>');
echo $array[1][''];
echo('</td>');
echo('<td>');
echo $array[2][''];
echo('</td>');
echo('</tr>');

//a counter that checks the length of the first array
$count = count( $array[0] );
$i = 1;

while( $i < $count ) {
        //a number is appended to _row- 
	$str = '_row-';
	$x = $str . $i;
	
	echo('<tr>');
	echo('<td>');
	echo $array[0][$x];
	echo('</td>');
	echo('<td>');
	echo $array[1][$x];
	echo('</td>');
	echo('<td>');
	echo $array[2][$x];
	echo('</td>');
	echo('</tr>');
	
	$i = $i + 1;
}

echo '</table>';

So the data is stored by columns, now rows, ie each field represents a column.

So if you have a table with 3 fields ( and I am assuming you’re using this plugin with the Smart Grid extension) then you need to do the following,

1. retrieve your 3 fields ($field1, $field2, $field3)

2. loop through each row 0, 1, 2 which are the field array indeces,


for($idx = 0; $idx < sizeof($field1); $idx++){
  //row($idx) would be $field1[$idx], $field2[$idx], $field3[$idx]
}
