如何为复选框组创建模板以避免服务器端代码重复?
How to create a template for checkbox groups to avoid code duplication at server side?
最近发现一个问题(whosebug.com/questions/30556100/how-to-uncheck-all-checkboxes-if-one-checkbox-checked)。现在,我想为 HTML 代创建一个模板,因为这似乎是避免代码重复的好主意。这就是我的 html 的生成方式:
// ---------------------------------------
// --- Populate "Body Type" dropdown list:
// ---------------------------------------
// for populate body types:
$bodytype = array();
// Select exsiting body type from database:
$prep_stmt = " SELECT id, name FROM body_type";
$stmt = $mysqli->prepare($prep_stmt);
if ($stmt) {
// Bind "$userId" to parameter.
//$stmt->bind_param('i', $userId);
// Execute the prepared query.
$stmt->execute();
$stmt->store_result();
// get variables from result.
$stmt->bind_result($id, $name);
// Fetch all the records:
while ($stmt->fetch()) {
// XSS protection as we might print these values
$name = preg_replace("/[^a-zA-Z0-9_\-]+/", "", $name);
$id = filter_var($id,FILTER_SANITIZE_NUMBER_INT);
$type = "<label class='checkbox-inline'>\n";
if ($name == 'Any'){
$type .= "<input type='checkbox' id='bodyTypeAny' name='bodyTypeCheck[]' value='{$id}'> {$name}\n";
} else {
$type .= "<input type='checkbox' id='' name='bodyTypeCheck[]' value='{$id}'> {$name}\n";
}
$type .= "</label>\n";
//Add body types to array
$bodytype[] = $type;
}
} else {
echo 'Database error';
}
// Close the statement:
$stmt->close();
unset($stmt);

我如何实现一个可以生成复选框组的函数,所以我会简单地将其称为函数。
希望有人能帮助我。
谢谢你。
在执行以下步骤之前,请将您的工作版本保存在某处,以确保您可以在需要时回滚。
您可以为模板创建一个 class,如下所示:
class TemplateEngine {
public static function getCheckboxTemplate($input, $templateName) {
$template = "";
foreach ($input as $element) {
$template .= "<label class='checkbox-inline'>\n";
$template .= "<input type='checkbox' ".(($element["name"] === "Any") ? ("id='".$templateName."Any'") : (""))." name='".$templateName."Check' value='".$element["id"]."'>".$element["name"]."\n";
$template .= "</label>\n";
}
return $template;
}
}
确保在一个单独的文件中创建 class,您也将在该文件中实现以后的模板,并且 require/include 该文件。然后你可以像这样使用它:
// ---------------------------------------
// --- Populate "Body Type" dropdown list:
// ---------------------------------------
$template = "";
// Select exsiting body type from database:
$prep_stmt = " SELECT id, name FROM body_type";
$stmt = $mysqli->prepare($prep_stmt);
if ($stmt) {
// Bind "$userId" to parameter.
//$stmt->bind_param('i', $userId);
// Execute the prepared query.
$stmt->execute();
$stmt->store_result();
// get variables from result.
$stmt->bind_result($id, $name);
$input = array();
// Fetch all the records:
while ($stmt->fetch()) {
$input[]= array("name" => preg_replace("/[^a-zA-Z0-9_\-]+/", "", $name), "id" => filter_var($id,FILTER_SANITIZE_NUMBER_INT));
}
$template = TemplateEngine::getCheckboxTemplate($input, "bodyType");
} else {
echo 'Database error';
}
// Close the statement:
$stmt->close();
unset($stmt);
而不是使用 $bodytype
array
,您可以简单地:
echo $template;
代码未经测试。如果有错别字,请告诉我:)
编辑:进一步模板化:
class TemplateEngine {
public static function getCheckboxTemplate($input, $templateName) {
$template = "";
foreach ($input as $element) {
$template .= "<label class='checkbox-inline'>\n";
$template .= "<input type='checkbox' ".(($element["name"] === "Any") ? ("id='".$templateName."Any'") : (""))." name='".$templateName."Check' value='".$element["id"]."'>".$element["name"]."\n";
$template .= "</label>\n";
}
return $template;
}
public static function getCheckboxDatabaseWrapperTemplate($tableName, $templateName, $mysqli) {
$template = "";
// Select exsiting body type from database:
$prep_stmt = " SELECT id, name FROM ".$tableName;
$stmt = $mysqli->prepare($prep_stmt);
if ($stmt) {
// Bind "$userId" to parameter.
//$stmt->bind_param('i', $userId);
// Execute the prepared query.
$stmt->execute();
$stmt->store_result();
// get variables from result.
$stmt->bind_result($id, $name);
$input = array();
// Fetch all the records:
while ($stmt->fetch()) {
$input[]= array("name" => preg_replace("/[^a-zA-Z0-9_\-]+/", "", $name), "id" => filter_var($id,FILTER_SANITIZE_NUMBER_INT));
}
$template = TemplateEngine::getCheckboxTemplate($input, $templateName);
} else {
echo 'Database error';
}
// Close the statement:
$stmt->close();
unset($stmt);
return $template;
}
