首先我解释一下我的问题:
我有两个表Job和JobCategory:
job:
-------------------------------------------------
| id | category_job_id | job_name | keywords |
-------------------------------------------------
JobCategory:
-------------------------
| id | categoty_name |
-------------------------
这两个表与外键相关" category_job_id"。
在此应用程序中,我使用的是Propel ORM。我希望使用三个字段关键字job_name和category_name进行搜索。
第一个字段是关键字是"输入"谁我可以写关键字,第二个字段是Category_name是"选择",类别列表。第三个字段是Job_name,是" select",作业名称列表,如果不为空,则忽略关键字字段。
我像这样制作搜索功能,但它对我不起作用:
public function searchFilter($job,$category,$keyword)
{
$order = isset($this->order) ? $this->order : Criteria::ASC;
$job = '%' .$job. '%';
$category = '%' .$category. '%';
$c = new Criteria();
$c->addJoin(JobPeer::CATEGORY_JOB_ID, JobCategoryPeer::ID);
if((null !== $category) AND ($category !== ""))
{
$c->addOr(JobCategoryPeer::CATEGORY_NAME,$category, Criteria::LIKE);
}
if((null !== $job) AND ($job !== ""))
{
$c->addOr(JobPeer::JOB_NAME,$job, Criteria::LIKE);
}
$query = JobQuery::create(null, $c)
->joinWith('Job.JobCategory')
->orderByDateOfJob($order);
if((null !== $keyword) AND ($keyword !== "")){
$keyword = '%' .$keyword. '%';
$query->filterByKeywords($keyword, Criteria::LIKE);
}
$results = $query->find();
return $results;
}
但搜索是所有情况都是错误的!

我觉得这样的事情会起作用。如果没有,您可以在发出find()
之前获取生成的SQL(见下文),以便您(和我们)可以看到输出可能是什么。
public function searchFilter($job,$category,$keyword)
{
$order = isset($this->order) ? $this->order : Criteria::ASC;
$query = JobQuery::create()->joinWith('JobCategory');
$conditions = array();
if((null !== $category) AND ($category !== ""))
{
$query->condition('catName', "JobCategory.CategoryName LIKE ?", "%$category%");
$conditions[] = 'catName';
}
if((null !== $job) AND ($job !== ""))
{
$query->condition('jobName', "Job.JobName LIKE ?", "%$job%");
$conditions[] = 'jobName';
}
if (sizeOf($conditions) > 1)
{
// join your conditions with an "or" if there are multiple
$query->combine($conditions, Criteria::LOGICAL_OR, 'allConditions');
// redefine this so we have the combined conditions
$conditions = array('allConditions');
}
// add all conditions to query (might only be 1)
$query->where($conditions);
if((null !== $keyword) AND ($keyword !== ""))
{
$query->filterByKeywords("%$keyword%", Criteria::LIKE);
}
$query->orderByDateOfJob($order);
$sql = $query->toString(); // log this value so we can see the SQL if there is a problem
return $query->find();
}
