如何在cakephp中连接条件数组

Question

根据条件获取DB结果

if($keyword!='')
  build condition;
  /*
    array('conditions' => array("AND" => array ("esl.esl_artistname LIKE"=>"%".$artistname."%",
    "esl.esl_songname LIKE"=>"%".$songname."%")),
    'limit' => $arrFind['limit'],
    'page'=>$arrFind['page']));
  */


if(!name!='')
  /* 
    array('conditions' => array("esl.esl_artistname LIKE"=>"%".$artistname."%"),
    'limit' => $arrFind['limit'],
    'page'=>$arrFind['page'] ))
  */

$this->find('all',condition);

如何做到这一点？如何连接两个条件？

Answer 1

为什么不初始化

conditions

数组并直接追加到它上面？

$conditions = array();
if( keyword != '' ) {
  array_push(
    'conditions'
    , array( "AND" => array ("esl.esl_artistname LIKE"=>"%".$artistname."%", "esl.esl_songname LIKE"=>"%".$songname."%" ) )
}

if( !name != '' ) {
   array_push( 'conditions', array("esl.esl_artistname LIKE"=>"%".$artistname."%")
}

$this->find( 'all', array( 'conditions' => $conditions, 'limit' => $arrFind['limit'], 'page' => $arrFind['page'];

Answer 2

我会做罗布·威尔克森建议的事情，但像这样：

$conditions = array();
if(keyword != '') {
    $conditions[] = array( "AND" => array ("esl.esl_artistname LIKE"=>"%".$artistname."%", "esl.esl_songname LIKE"=>"%".$songname."%" ) );
}

if(!name != '') {
    $conditions[] = array("esl.esl_artistname LIKE"=>"%".$artistname."%");
}

$this->find( 'all', array( 'conditions' => $conditions, 'limit' => $arrFind['limit'], 'page' => $arrFind['page'];

Answer 3

连接条件可以通过以下方式完成：

$condition1 = array('Model1.field1 LIKE'=>'%'.$value.'%', 'Model1.field2'=>2);
$condition2 = array('Model2.field2 LIKE'=>'%'.$value.'%', 'Model2.field2'=>1);

$this->MyModel->find('all', array('conditions'=>am($condition1, $condition2)));

am 是蛋糕的 array_merge 的快捷方式。
