我已经多次检查过phpMyAdmin中的查询,并且确定它们绝对是正确的。此外,如果我手动写入循环3次,设置2,3,4而不是递增计数器,它仍然只显示最后一行中的一列。前两行结果准确无误。
foreach($row as $rec)
基本上是从另一个打印表头的查询中运行了17次。
$by_type1 = array("First","Second+","Final");
$counter = 2; //this counter represents type of interview (2-First, 3-Second+, 4-Final)
foreach ($by_type1 as $type1)
{
$table_row = '<tr><td class="rborder">'.$type1.'</td>';
foreach ($row as $rec)
{
$id=$rec['id'];
$qry2 = "SELECT
CONCAT( r.fname, ' ', r.lname ) AS rname,
ch.status_id as Type,
count(ch.status_id) as number
FROM candidateJoborderHistory ch
LEFT JOIN candidates_info c ON ch.candidate_id = c.candidate_id
LEFT JOIN recruiters r ON c.recruiter_id=r.recruiter_id
LEFT JOIN interviewtypes i ON ch.interview_id = i.interview_id
WHERE c.recruiter_id = $id AND UNIX_TIMESTAMP(ch.date_interview) BETWEEN 1401667200 AND
1402099200 AND ch.status_id = $counter
group by ch.status_id";
global $conn;
$conn->open();
$stmt2 = $conn->prepare($qry2);
$stmt2->execute();
$row2 = $stmt2->fetchAll();
foreach($row2 as $row_x)
{
$table_row .= '<td>'.$row_x['number'].'</td>';
}
}
$table_row .='</tr>';
echo $table_row . "\n";
$counter++;
}
我想要的是:
First 6 6 4 4 11 6 12 3
Second+ 3 1 2 1 3
Final 3 2 1 4 1
但我得到的是:
First 6 6 4 4 11 6 12 3
Second+ 3 1 2 1 3
Final 3
答案 0 :(得分:1)
我认为这是一种MySQL方法,我对您的代码进行了一些更改并对其进行了解释:
$by_type1 = array(2=>"First", 3=>"Second+", 4=>"Final");
$counter = 2; //this counter represents type of interview (2-First, 3-Second+, 4-Final)
// Open connection first.
global $conn;
$conn->open();
// Using key => value array gets code simple
foreach ($by_type1 as $counter=>$type1)
{
$table_row = '<tr><td class="rborder">'.$type1.'</td>';
foreach ($row as $rec)
{
$id=$rec['id'];
$qry2 = "SELECT
CONCAT( r.fname, ' ', r.lname ) AS rname,
ch.status_id as Type,
count(ch.status_id) as number
FROM candidateJoborderHistory ch
LEFT JOIN candidates_info c ON ch.candidate_id = c.candidate_id
LEFT JOIN recruiters r ON c.recruiter_id=r.recruiter_id
LEFT JOIN interviewtypes i ON ch.interview_id = i.interview_id
WHERE c.recruiter_id = $id
AND UNIX_TIMESTAMP(ch.date_interview)
BETWEEN 1401667200 AND 1402099200
AND ch.status_id = $counter
GROUP BY ch.status_id";
$res = $conn->prepare($qry2);
$res->execute();
// Loop to get data...
while($row_x = $res->fetch(PDO::FETCH_ASSOC))
{
$table_row .= '<td>'.$row_x['number'].'</td>';
}
}
$table_row .='</tr>';
echo $table_row . "\n";
}
$conn->close();
代码未经过测试,但如果您有任何疑问,请询问。希望它有所帮助!
