这是一个非营利组织的网站代码,在有需要的情况下赞助儿童;赞助商可以登录他/她的用户帐户,每三个月查看一系列可以下载的教父文件(照片,信件等)。
此代码应选择在名为“files”的表中注册的可用文件,并按相应的时间段显示结果,为四个三个月的时间段。
示例:
2016年第一季度
档案A1 :::档案B1 :::档案C1
2016年第二季度
档案A2 :::档案B2 :::档案C2
等
到目前为止的问题是,如果我从'while($ updates - > fetch())'中删除'$ file statement',页面会显示有序时段,或者显示所有时段的所有文件使用'$ file statement'清除'$ updates语句'。
有人能帮助我吗?
<?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">

</div>
</button>
</form>
</div>
';
}
$files->free_result();
echo '
</div>

}
$updates->free_result();
echo '
</div>

这样的事情应该有效;您使用变量($CurrentFilesDate
)来跟踪期间,当您看到它发生变化时,您会在其中添加一个新标题。
$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>';
这段代码非常难看,你应该将PHP和HTML分开。我建议使用DB循环在您需要的结构中构建一个数组,然后在只包含简单echo
语句的HTML模板中循环它。
