$ wpdbから行の結果を解析する方法-> 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;}

常にWordPressコーデックスを試してください: http://codex.wordpress.org/Class_Reference/wpdb#SELECT_Generic_Results

基本的にデフォルトの構文が与えられている場合、ここでの変数$ rowは、結果を含むオブジェクトです.または、結果のタイプ(数値配列、連想配列)を指定することもできます.

結果が1つだけだとすると、$ row->idと$ row->nameで情報が得られます.

複数の結果が返される場合は、オブジェクトのエントリをループする必要があります.

1行だけ戻ると予想される場合は、$ wpdb->get_rowを使用してみてください 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

連想配列として使用するには:

 $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
 

使用法

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

他の形式を取得するには、 $wpdb->get_results() のドキュメント. Pippinの答えは、ほとんどのオブジェクトの使用に適しています.

1つの行を数値インデックス付き配列として使用するには

 $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 . ' ';
 

キーがデータベースの主キーである配列の1つの行を使用する(多くの場合id列).おそらく連想配列法よりも効率的です.

 $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;

このコードは私にぴったりです:

 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;}
