Foreach multiple result set print in HTML table - php

Question

I am trying to pull two results from 2 sql statements and print into HTML table.
but some how results are not coming correct.please hel me to resolve.
Below is code 2nd result is not printing correct results - duplicated results.
<?php
global $wpdb;
$result1=$wpdb->get_results("select post_name,id,cat from wp_posts where post_name like '%java%');
$result2=$wpdb->get_results("select post_name,id,cat from wp_posts where post_name like '%oracle%');
?>
<table id="table_id">
<thead>
<tr>
<th>JAVA</th>
<th>ORACLE</th>
</tr>
</thead>
<tbody>
<?php foreach($result1 as $rows1) { ?>
<?php foreach($result2 as $rows2) { ?>
<tr>
<td> <?php echo $rows1->post_name ; ?> </td>
<td> <?php echo $rows2->post_name ; ?> </td>
</tr>
<?php
}
?>
<?php
}
?>

Answer 1

global $wpdb;
$result1=$wpdb->get_results("SELECT post_name,id,cat FROM wp_posts WHERE post_name LIKE '%java%'");
$result2=$wpdb->get_results("SELECT post_name,id,cat FROM wp_posts WHERE post_name LIKE '%oracle%'");
After getting to objects , we put the required values in two arrays so that we can create a multi-dimensional array.
$result_one = array();
$result_two = array();
//putting values in array
foreach ($result1 as $result) {
$result_one[] = $result->post_name;
}
foreach ($result2 as $result) {
$result_two[] = $result->post_name;
}
//Creating a multi-dimensional array so that we can print two columns easily
$results = array(
$result_one,
$result_two,
);
//Initialising the variables to be used as counters and array indexes.
$i = 0; $j = 0; $k = 0; $p = 1;
//getting length of array
$array_length = count($result_one);
Now start two loops to fetch data from multi-dimensional array created.
In this case: To create the table properly we need values in this order:
$results[0][0], $results[1][0], $results[0][1], $results[1][1],
$results[0][2], $results[1][2] and so on.
So we have to create loops accordingly.
while ($i < 2) {
while ($j < $array_length) {
if (fmod($p,2)) echo '<tr>'; // So that <tr> will be printed only after two <td>
echo "<td>". $results[$i][$j]. "</td>";
if($i == 0) { $i = 1; } else { $i =0; } // Toggling values of $i from 0 to 1.
$k++;
if(fmod($k, 2) == 0){ $j ++; } // Increasing $j after 2 steps.
$p++;
if (fmod($p,2)) echo '</tr>';
}
$i ++;
}
If you need three columns:
Repeat steps one two and three so that you can create an array like this:
$results = array(
$result_one,
$result_two,
$result_three,
);
Change first while loop to
while ($i < 3)
And change the following statements as:
if (fmod($p,3)) echo '<tr>';
if($i == 0) { $i = 1; } elseif ($i == 1) {$i=2} else { $i = 0; }
if(fmod($k, 3) == 0){ $j ++; }
if (fmod($p,3)) echo '</tr>';
I hope you got better understanding now and can make the required changes yourself.
This seems complicated. But this should work. Please try.
Anyone please feel free to edit the while loop to make it simpler.

Answer 2

something i missed out for 3rd result array.please correct me.
$results = array(
$result_one,
$result_two,
$result_three,
);
$i = 0; $j = 0; $m = 0; $k = 0; $p = 1;
$array_length = count($result_one);
?>
<table id="table_id">
<thead>
<tr>
<th>ORACLE</th>
<th>JAVA</th>
<th>SAP</th>
</tr>
</thead>
<tbody>
<?php while ($i < 3) {
while ($j < $array_length) {
if (fmod($p,3)) echo '<tr>';
echo "<td>" . $results[$i][$j] . "</td>";
if($i == 0) { $i = 1; } elseif ($i == 1) {$i=2} else { $i = 0; }
$k++;
if(fmod($k, 3) == 0){ $j ++; }
$p++;
if (fmod($p,3)) echo '</tr>';
}
$i ++;
}
?>
