这是一个非营利组织的网站代码,该组织在有需要的情况下赞助儿童;赞助商可以登录到他/她的用户帐户,每三个月查看一次可以下载的其教子的一系列文件(照片,信件等)。
此代码应选择在名为“文件”的表中注册的可用文件,并显示按其相应期间(三个月的四个期间)排序的结果。
例:
2016年第一季度
存档A1 :::存档B1 :::存档C1
2016年第二季度
存档A2 :::存档B2 :::存档C2
等等。
到目前为止的问题是,如果我从“ while($ updates-> fetch())”中删除了“ $ file statement”,则页面显示有序期间,或者显示所有期间的所有文件以及“ $”文件语句”,而不是“ $ updates语句”。
有人可以帮我吗?
<?php
...
// This relate the file with its user.
$FileCode = $_SESSION["Card"];
echo '
<div class="contentLogIn">
<div class="ctlg-ins">
<p class="startText">My files</p>
</div>
';
// I use SELECT DISTINCT because in the table 'files' multiple values can have the same period but i only want to know if the period have values not how much.
$updates = $db->prepare("SELECT DISTINCT Trimester, Quarter, Year FROM files WHERE FileCode=? ORDER BY Year DESC, Quarter DESC, Trimester DESC");
if ($updates === FALSE) {trigger_error($db->mysqli->error, E_USER_ERROR);}
$updates->bind_param("s", $FileCode);
$updates->execute();
$updates->bind_result( $Trimester, $Quarter, $Year );
while ( $updates->fetch() ) {
// For every single period shows its title.
if ( isset($Year, $Quarter) ) {
$FilesDate = $Trimester . " quarter of " . $Year; // Output example: *First quarter of 2016*
} else {
$FilesDate = "There's no available files.";
}
echo '
<div class="W100">
<p class="startTextDesc">' . $FilesDate . '</p>
</div>
<div class="A12">
';
$files = $db->prepare("SELECT Type, Class, SRC FROM files WHERE FileCode=? AND Quarter=? AND Year=?");
if ($files === FALSE) { trigger_error($db->mysqli->error, E_USER_ERROR); }
$files->bind_param("sss", $FileCode, $Quarter, $Year);
$files->execute();
$files->bind_result($Type, $Class, $SRC);
while ( $files->fetch() ) {
// This is the file that it is supposed to be displayed under its period title - like the example i post before.
echo '
<div class="FileCont CustomPointer">
<form method="POST" action="/php/File.Download.php">
<input type="hidden" name="fileButton" id="fileButton" value="' . $SRC . '">
<button type="submit" class="buttonFile-download">
<div class="CustomPointer">
<p style="...">' . $Type . '</p>
</div>
</button>
</form>
</div>
';
}
$files->free_result();
echo '
</div>
';
}
$updates->free_result();
echo '
</div>
';
...
?>
最佳答案
这样的事情应该起作用;您使用变量($CurrentFilesDate
)来跟踪时间段,并且当它看到变化时,您将放一个新的标题。
$CurrentFilesDate = "";
$updates = $db->prepare("SELECT Trimester, Quarter, Year, Type, Class, SRC FROM files WHERE FileCode=? ORDER BY Year DESC, Quarter DESC, Trimester DESC");
if ($updates === FALSE) {
trigger_error($db->mysqli->error, E_USER_ERROR);
}
$updates->bind_param("s", $FileCode);
$updates->execute();
$updates->bind_result( $Trimester, $Quarter, $Year, $Type, $Class, $SRC );
while ( $updates->fetch() ) {
$FilesDate = $Trimester . " quarter of " . $Year;
if ($FilesDate != $CurrentFilesDate) {
if (!empty($CurrentFilesDate)) {
echo '</div>';
}
echo '
<div class="W100">
<p class="startTextDesc">' . $FilesDate . '</p>
</div>
<div class="A12">
';
$CurrentFilesDate = $FilesDate;
}
echo '
<div class="FileCont CustomPointer">
<form method="POST" action="/php/File.Download.php">
<input type="hidden" name="fileButton" id="fileButton" value="' . $SRC . '">
<button type="submit" class="buttonFile-download">
<div class="CustomPointer">
<p style="...">' . $Type . '</p>
</div>
</button>
</form>
</div>
';
}
echo '</div>';
这段代码非常丑陋,您应该将PHP和HTML分开。我建议使用DB循环在所需的结构中构建一个数组,然后在仅包含简单
echo
语句的HTML模板中对其进行循环。
