一次显示组标题的有效方法-PHP/MySQL/jQuery
MySQL中有三个表：员工、分支机构和部门。我需要以以下方式显示信息： 亚特兰大分行配送部Phillip J.Fry电话：123456 工程部Turanga Leela电话：123457 本德·罗德里格斯电话：123458 当前的简单PHP代码是： 1使用联接从三个表中获取行简单选择查询 2将它们放入mysql\u fetch\u assoc行 3使用PHP While循环显示 结果如下： 亚特兰大分行配送部Phillip J.Fry电话：123456 亚特兰大分行工程部Turanga Leela电话：123457 亚特兰大分行工程部Bender Rodriguez电话：123458 您可以推荐什么技术JS、jQuery、Ajax或方法，这样我就可以只使用一个查询来提取行信息，而不会重复分支名称和部门名称？ 更新：如果我使用While循环将分支名称放在循环之外，将有多个循环：1获取分支，2获取部门，3获取该部门的所有员工。环 更新：共享代码：一次显示组标题的有效方法-PHP/MySQL/jQuery,php,jquery,mysql,Php,Jquery,Mysql,MySQL中有三个表：员工、分支机构和部门。我需要以以下方式显示信息： 亚特兰大分行配送部Phillip J.Fry电话：123456 工程部Turanga Leela电话：123457 本德·罗德里格斯电话：123458 当前的简单PHP代码是： 1使用联接从三个表中获取行简单选择查询 2将它们放入mysql\u fetch\u assoc行 3使用PHP While循环显示 结果如下： 亚特兰大分行配送部Phillip J.Fry电话：123456 亚特兰大分行工程部Turanga Lee
从sql中获得的结果应该是一个数组，因此使用while循环迭代抛出数组，同时回显当前索引的结果
$result = mysql_query($query, $connection) or die(mysql_error());
$newarray = array();
$i = 0;
while ($row = mysql_fetch_assoc($result)) {
$newarray[$i]['deptName'] = $row['deptName'];
$newarray[$i]['fName'] = $row['fName'];
$newarray[$i]['lName'] = $row['lName'];
$i++;
}
<h2><?php echo $newarray[0]['branchName']; ?></h2>
while($newarray){
?>
<?php if ($newarray['deptName']) echo "<h3>" . $newarray['deptName'] . "</h3>"; ?>
<h4><?php echo $newarray['fName'] . " " . $newarray['lName']; ?></h4></p>
}
<?php
$deptName;
while($row = mysql_fetch_assoc($result))
{
if ($row['deptName'])
{
if ($deptName != $row['deptName'])
{
echo "<h3>" . $row['deptName'] . "</h3>";
$deptName = $row['deptName'];
}
}
}
?>
这就是它所做的：
$query = "SELECT Employees.lName, Employees.fName, Employees.mName, Position.position, ".
"department.deptName, department.deptId, ".
"Branch.branchName, Branch.branchId, ContactInformation.* ".
"FROM Employees ".
"LEFT JOIN Position ".
"ON Employees.position = Position.id ".
"LEFT JOIN Department ".
"ON Employees.department = Department.deptId ".
"LEFT JOIN Branch ".
"ON Employees.branch = Branch.branchId ".
"LEFT JOIN ContactInformation ".
"ON Employees.contactInformation = ContactInformation.id ".
"ORDER BY Employees.branch, Employees.department ASC;";
$result = mysql_query($query, $connection) or die(mysql_error());
$arrayOfEmployees = array();
while ($row = mysql_fetch_assoc($result)) {
$arrayOfEmployees[($row['branchName'])][($row['deptName'])][] = array(
'lName' => $row['lName'],
'fName' => $row['fName'],
'mName' => $row['mName'],
'position' => $row['position'],
'lPhone1' => $row['lPhone1'],
'lPhone2' => $row['lPhone2'],
'mPhone' => $row['mPhone'],
'fax' => $row['fax'],
'office' => $row['office'],
'email' => $row['email']
);
}
foreach($arrayOfEmployees as $branchName => $arrayOfDepartments) {
echo "<h2>".$branchName."</h2>";
foreach($arrayOfDepartments as $deptName => $arrayOfEmployeeContacts) {
echo '<h3>',htmlentities($deptName),'</h3>';
foreach($arrayOfEmployeeContacts as $employeeContacts) {
echo "<h4>".$employeeContacts["lName"]." ".$employeeContacts["fName"]." ".$employeeContacts["mName"]."</h4>";
echo "<p>";
if($employeeContacts["position"]) echo $employeeContacts["position"]."<br>";
$num = $employeeContacts["lPhone1"];
if($employeeContacts["lPhone1"]) echo "+".substr($num,0,1)." (".substr($num,1,4).") "." ".substr($num,5,2)."-".substr($num,7,2)."-".substr($num,9,2)."<br>";
$num = $employeeContacts["lPhone2"];
if($employeeContacts["lPhone2"]) echo "+".substr($num,0,1)." (".substr($num,1,4).") "." ".substr($num,5,2)."-".substr($num,7,2)."-".substr($num,9,2)."<br>";
$num = $employeeContacts["mPhone"];
if($employeeContacts["mPhone"]) echo "+".substr($num,0,1)." (".substr($num,1,3).") "." ".substr($num,4,3)."-".substr($num,7,2)."-".substr($num,9,2)."<br>";
$num = $employeeContacts["fax"];
if($employeeContacts["fax"]) echo "+".substr($num,0,1)." (".substr($num,1,4).") "." ".substr($num,5,2)."-".substr($num,7,2)."-".substr($num,9,2)."<br>";
if($employeeContacts["email"]) echo "<a href=\"mailto:".$employeeContacts["email"]."\">".$employeeContacts["email"]."</a><br>";
if($employeeContacts["office"]) echo "Кабинет — ".$employeeContacts["office"];
echo "</p>";
}
}
}
我会这样做的 使用数据创建多维数组，并遍历该数组以呈现输出 这在内存使用方面不是最有效的，但除非您有数千行数据，否则这可能不会成为问题 这样做的好处是，html呈现代码更简单、更容易理解，而且sql和html不会混合使用。这有利于代码维护
<?php
// Create connection
$connection = mysql_connect('localhost','root', '') or die('Connection error.');
mysql_query("SET NAMES 'utf8'", $connection);
mysql_select_db("eReference");
// Check Employees
$query = "SELECT Employees.fName, Employees.lName, Department.deptName, Branch.branchName, ".
"FROM Employees ".
"LEFT JOIN Department ".
"ON Employees.department = Department.id ".
"LEFT JOIN Branch ".
"ON Employees.branch = Branch.id ;";
// note you probably want to add an order by statement here too, to ensure consistent sorting
$result = mysql_query($query, $connection) or die(mysql_error());
$data = array();
// build a multi-dimensional array from the result set
while ($row = mysql_fetch_assoc($result)) {
$data[($row['branchName'])][($row['deptName'])][] = array(
'name' => "{$row['fName']} {$row['lName']}",
'phone' => $row['phone'] // add phone, doesn't exist in original query, but just to illustrate how it would work
);
}
// sql finishes here
?>
<?php
// html rendering
// use htmlentities to escape any html chars, such as < > etc
foreach ($data as $branchName => $departments) {
echo '<h2>',htmlentities($branchName),'</h2>';
foreach ($departments as $deptName => $employees) {
foreach ($employees as $employee) {
echo '<h3>',htmlentities($deptName),'</h3>';
echo '<h4>',htmlentities($employee['name']),'</h4>';
echo '<h4>',htmlentities($employee['phone']),'</h4>';
}
}
}

你不应该在你的圈子里呼应亚特兰大海滩。把它放在while循环之外…也许它会工作…是的，但是我会有多个查询：1获取所有分支，2获取所有员工。请共享您的代码我很乐意这样做。给我几分钟。我将尝试此解决方案，但复制$row中已存在的阵列是否是一个好主意？谢谢您，Sanj，感谢您的时间和回复，我非常感谢。我尝试了这段代码，但是，它在视觉上比使用If子句的方法花费了更多的时间。我将发布我是如何解决这个问题的。这也是我所想的。我也要试试这个。寻找最有效的方法：-Sandesh，谢谢你的提示。我使用了迭代，在SQL查询中做了一些小改动，一切都很好。我将发布另一个答案。Prodeep，我明白你的逻辑。事实上，这很好，但是为了使解决方案动态化，最好按照Sandesh的建议使用变量并对SQL查询进行一些小的更改。我会在五个小时后发布答案声誉不够。你是否测试过如果你删除了一个分支并且你的分支id不再连续会发生什么？我认为@Prodeep的概念是一个更好的通用解决方案。因此，我遵循您的方法，从逻辑上讲，它比我最初在代码中使用的方法工作得更好。
