我需要帮助启用/禁用我网站的某些部分。
<p>Disabled Sections:</p>
<form id="e-d-check" method="post">
<input type="checkbox" name="SRS" onchange="document.getElementById('e-d-check').submit()">SkiRegionSimulator 2012</input>
<input type="checkbox" name="Bilder" onchange="document.getElementById('e-d-check').submit()">Bilder</input>
<input type="checkbox" name="KWS" onchange="document.getElementById('e-d-check').submit()">Klimawandel-Stunde</input>
</form>
<table>
<tr>
<th>Name</th>
<th>Größe</th>
<th>Datum</th>
<th>Download</th>
</tr>
<?php
if (isset($_POST['SRS'])) {
echo 'Disabled SkiRegionSimulator 2012';
} else {
include'SRS.php';
}
?>
每次我取消选中复选框时，它都会再次检查自己。。。
检查这是否适用于您：
<?php
$disabled = array();
$disabled['SRS'] = isset($_POST['SRS']) && (int)$_POST['SRS'] === 1;
$disabled['Bilder'] = isset($_POST['Bilder']) && (int)$_POST['Bilder'] === 1;
$disabled['KWS'] = isset($_POST['KWS']) && (int)$_POST['KWS'] === 1;
?>
<p>Disabled Sections:</p>
<form id="e-d-check" method="post">
<input type="checkbox" value="1" <?php if($disabled['SRS'] === true) echo "checked"; ?> name="SRS" onchange="document.getElementById('e-d-check').submit()">SkiRegionSimulator 2012</input>
<input type="checkbox" value="1" <?php if($disabled['Bilder'] === true) echo "checked"; ?> name="Bilder" onchange="document.getElementById('e-d-check').submit()">Bilder</input>
<input type="checkbox" value="1" <?php if($disabled['KWS'] === true) echo "checked"; ?> name="KWS" onchange="document.getElementById('e-d-check').submit()">Klimawandel-Stunde</input>
</form>
<table>
<tr>
<th>Name</th>
<th>Größe</th>
<th>Datum</th>
<th>Download</th>
</tr>
<?php
if ($disabled['SRS'] === true) {
echo 'Disabled SkiRegionSimulator 2012';
} else {
include'SRS.php';
}
?>
我们使用（猜测！）checked属性来控制选中哪个复选框。如果使用XHTML，则将checked更改为checked="checked"
一种不同但相似的提交onclick方法。
<?php
$check_SRS = "";
$check_Bilder = "";
$check_KWS = "";
if (isset($_POST['SRS']) && intval($_POST['SRS']) == 1) { $check_SRS = "checked";}
if (isset($_POST['Bilder']) && intval($_POST['Bilder']) == 1) { $check_Bilder = "checked";}
if (isset($_POST['KWS']) && intval($_POST['KWS']) == 1) { $check_KWS = "checked";}
?>
<p>Disabled Sections:</p>
<form id="e-d-check" method="post">
<input type="checkbox" name="SRS" value="1" onclick="submit()" <?php echo htmlspecialchars($check_SRS); ?>>SkiRegionSimulator 2012</input>
<input type="checkbox" name="Bilder" value="1" onclick="submit()" <?php echo htmlspecialchars($check_Bilder); ?>>Bilder</input>
<input type="checkbox" name="KWS" value="1" onclick="submit()" <?php echo htmlspecialchars($check_KWS); ?>>Klimawandel-Stunde</input>
</form>
<table>
<tr>
<th>Name</th>
<th>Größe</th>
<th>Datum</th>
<th>Download</th>
</tr>
<?php
if (isset($_POST['SRS']) && intval($_POST['SRS']) == 1) {
echo 'Disabled SkiRegionSimulator 2012';
} else {
include'SRS.php';
}
?>
elseif语句的一个版本，以适应被认为是另一个的内容，包括取决于复选框的状态的内容-如果只能选中一个：
<?php
if(intval($_POST['SRS']) == 1){
echo 'Disabled SkiRegionSimulator 2012';
}elseif(intval($_POST['SRS']) != 1){
include'SRS.php';
}elseif(intval($_POST['Bilder']) == 1){
echo 'Disabled Bilder';
}elseif(intval($_POST['Bilder']) != 1){
include'Bilder.php';
}elseif(intval($_POST['KWS']) == 1){
echo 'Disabled KWS';
}elseif(intval($_POST['KWS']) != 1){
include'KWS.php';
}
?>
如果可以检查多个：
<?php
if(intval($_POST['SRS']) == 1){
echo 'Disabled SkiRegionSimulator 2012';
}else{
include'SRS.php';
}
if(intval($_POST['Bilder']) == 1){
echo 'Disabled Bilder';
}else{
include'Bilder.php';
}
if(intval($_POST['KWS']) == 1){
echo 'Disabled KWS';
}else{
include'KWS.php';
}
?>
