Cómo analizar los resultados de las filas de $ wpdb -> get_results

 foreach( $wpdb->get_results("SELECT * FROM your_table_name WHERE id LIKE' . $id . ';") as $key => $row) {
// each column in your row will be accessible like this
$my_column = $row->column_name;}

// each column in your row will be accessible like this

Básicamente dada la sintaxispredeterminada,la variable $fila aquíes un objeto que contiene sus resultados.Alternativamente,podríaespecificarel TIPO de resultado (matriznumérica,matriz asociativa).

Asumiendo solo un resultado,$ row->id y $ row->name deberían darle lainformación.

Si obtienemás de un resultado,querrá recorrer lasentradas del objeto.

Si soloespera unafila atrás,intente usar $ wpdb->get_row http://codex.wordpress.org/Class_Reference/wpdb#SELECT_a_Row

Always Try the WordPress Codex: http://codex.wordpress.org/Class_Reference/wpdb#SELECT_Generic_Results

Essentially given the default syntax, the variable $row here is an object containing your results. You could alternately specify the TYPE of result (numeric array, associative array).

Assuming just one result, then $row->id and $row->name should give you the information.

If you get back more than one result, you'd want to loop over the entries in the object.

If you are expecting just one row back, then try using $wpdb->get_row http://codex.wordpress.org/Class_Reference/wpdb#SELECT_a_Row

Para usar como unamatriz asociativa:

 $obj=[];
$rows =  $wpdb->get_results( 'SELECT * FROM `tbl_name` WHERE `id` = '.$obj_id , ARRAY_A);
foreach($rows as $row){  $obj=$row; break; }

// $obj is now the selected row if a match was found
 

Uso

 $something = $obj['column_name'];
foreach($obj as $col => $val)
    echo $col . ': ' . $val . PHP_EOL . '<br />';
 

Para obtener otrosformatos,simplemente cambie ARRAY_Abasadoen documentación de $wpdb->get_results() . La respuesta de Pippines apropiadapara lamayoría de los objetos.

Para usar unafila como unamatrizindexadanuméricamente

 $rows =  $wpdb->get_results( 'SELECT * FROM `tbl_name` WHERE `id` = '.$obj_id , ARRAY_N);
foreach($rows as $row){  $obj=$row; break; }

//Usage
foreach($obj as $col_value) echo $col_value . ' ';
 

Para usar unafilaen unamatriz cuyas claves son la claveprincipal de subase de datos (amenudo una columna id). Posiblementemáseficiente queelmétodo dematriz asociativa.

 $rows =  $wpdb->get_results( 'SELECT * FROM `tbl_name` WHERE `id` = '.$obj_id ,  OBJECT_K);
$obj = $rows[ $obj_id ];

//Usage

$something = $obj->column_name;

//Remember you can loop over objects too
foreach($obj as $col => $val)
    echo $col . ': ' . $val . PHP_EOL;
 

To use as an associative array:

$obj=[];
$rows =  $wpdb->get_results( 'SELECT * FROM `tbl_name` WHERE `id` = '.$obj_id , ARRAY_A);
foreach($rows as $row){  $obj=$row; break; }

// $obj is now the selected row if a match was found

Usage

$something = $obj['column_name'];
foreach($obj as $col => $val)
    echo $col . ': ' . $val . PHP_EOL . '<br />';

To get other formats, simply change ARRAY_A based on the documentation for $wpdb->get_results(). Pippin's answer is appropriate for most object use.

To use one row as an numerically indexed array

$rows =  $wpdb->get_results( 'SELECT * FROM `tbl_name` WHERE `id` = '.$obj_id , ARRAY_N);
foreach($rows as $row){  $obj=$row; break; }

//Usage
foreach($obj as $col_value) echo $col_value . ' ';

To use one row in an array whose keys are the primary key from your database(often an id column). Possibly more efficient than the associative array method.

$rows =  $wpdb->get_results( 'SELECT * FROM `tbl_name` WHERE `id` = '.$obj_id ,  OBJECT_K);
$obj = $rows[ $obj_id ];

//Usage

$something = $obj->column_name;

//Remember you can loop over objects too
foreach($obj as $col => $val)
    echo $col . ': ' . $val . PHP_EOL;

Este códigofuncionaperfectamenteparamí:

 global $wpdb;
$table_name = "my_table_name";
$myrows = $wpdb->get_results( "SELECT `id`, `name` FROM ".$table_name);
    foreach ($myrows as $details) {
      echo $details->id;
      echo $details->name;}    
 

This code work perfect for me:

global $wpdb;
$table_name = "my_table_name";
$myrows = $wpdb->get_results( "SELECT `id`, `name` FROM ".$table_name);
    foreach ($myrows as $details) {
      echo $details->id;
      echo $details->name;}
