Retrieve Data from Database using Shortcode - php

Question

I am trying to retrieve data from a wordpress table using a shortcode function I found. It works and retrieves the data for all the columns. When I try to specify the columns I want it still give me everything. Ultimately what I am trying to do is retrieve the data for the columns I want and style that data using css (not in a table format). I am new to php so I was wondering if anyone could let me know if this is even possible using shortcodes. If it is possible any help would be appreciated. Thank you in advance, Randy
Here is the code I am using:
if ( !defined( 'WP_FD_ABSPATH' ) )
define( 'WP_FD_ABSPATH', plugin_dir_path( __FILE__ ) );
function wp_first_shortcode($atts){
global $wpdb;
$a = shortcode_atts( array(
'table_name' => ",
'columns' => ",
), $atts );
$showcolumns=array();
if($a['columns']!=""){
$column=$a['columns'];
$showcolumns=explode(',',$a['columns']);
}
else{
$column='*';
$get_columns=$wpdb->get_results("describe ".$a['table_name']."");
foreach($get_columns as $fields) $showcolumns[]=$fields->Field;
}
$columncount=count( $showcolumns);
$result_query=$wpdb->get_results( "select $column from ".$a['table_name']."");
echo '<table><tr>';
for($i=0;$i<$columncount;$i++) echo '<th>'.$showcolumns[$i].'</th>';
echo '</tr>';
foreach($result_query as $result_row){
echo '<tr>';
for($i=0;$i<$columncount;$i++) echo '<td>'.$result_row->$showcolumns[$i].'</td>';
echo '</tr>';
}
echo '</table>';
}
add_shortcode('fetchdata', 'wp_first_shortcode');
function table_value_function() {
query_value(array('orderby' => 'date', 'order' => 'DESC' , 'showvalues' => ""));
wp_reset_query();
return $return_string;
}
?>
Here is the shortcode I am using:
[fetchdata table_name='my_wp_table' columns ='Display_Name' 'First_Name' 'Last_Name' 'Address_1' 'Address_2' 'City' 'State' 'Phone']

Answer 1

Ok, I think you just want to get rid of the table as you want to style it with CSS. Please follow the code below:
echo '<div class="something">';
for($i=0;$i<$columncount;$i++) echo '<h1>'.$showcolumns[$i].'</h1>';
foreach($result_query as $result_row){
echo '<div class="something_2">';
for($i=0;$i<$columncount;$i++) echo '<p>'.$result_row->$showcolumns[$i].'</p>';
echo '</div>';
}
echo '</div>';
}
Hope, it helps.
