Problem:
Yo need to access to any database table connected to your wordpress or maybe an external one to extract any information and process it.
Solution:
Use this TestSQLand add is to your wordpress functions.php of "Code Snipper" plugin:
function TestSQL_Function( $atts ) {
$link = mysqli_connect("localhost", "user", "****", "DATABASENAME");
$sql = "SELECT * FROM table";
if($result = mysqli_query($link, $sql)){
if(mysqli_num_rows($result) > 0){
while($row = mysqli_fetch_array($result)){
$line = $line.$row['fielname1']."(".$row['fieldname2'].")";
}
return $line;
// Free result set
mysqli_free_result($result);
} else{
return "No records matching your query were found.";
}
} else{
return "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
// Close connection
mysqli_close($link);
}
add_shortcode( 'TestSQL', 'TestSQL_Function' );
Now, you only need to add the wordpress shortcut [TestSQL] in your wordpres post or page.
