每当我尝试更改某些内容时,我都会收到标题中提到的错误。我试着查了一下,但我真的不明白我找到的答案。导致此错误的原因以及如何修复它。例如,我尝试更改一个 href 链接,但我得到了这个错误,不知道是什么原因造成的。在我认为它与您的 php 代码标头的顺序有关之前,应该始终位于正文之前,之后您将无法再更改标头。但是,如果像 href 链接这样的小东西会导致它,那么就会发生其他事情。
警告:无法修改标头信息 - 标头已由(输出开始于 /home/nieuwsman/domains/cdwp.publiceer.net/public_html/wp-content/themes/wpoupon_mollie/ideal.class.php:1)在 /home/ nieuwsman/domains/cdwp.publiceer.net/public_html/wp-content/themes/wpoupon_mollie/functions.php 在第 28 行
function wpoupon_redirect_to_mollie() {
require_once('ideal.class.php');
if (!in_array('ssl', stream_get_transports()))
{
echo "<h1>Foutmelding</h1>";
echo "<p>Uw PHP installatie heeft geen SSL ondersteuning. SSL is nodig voor de communicatie met de Mollie iDEAL API.</p>";
exit;
}
$partner_id = 823997;
$amount = $_POST['amount'];
$description = $_POST['item_name'];
$return_url = $_POST['return'];
$report_url = $_POST['notify_url'];
$iDEAL = new iDEAL_Payment($partner_id);
//$iDEAL->setTestMode();
if (isset($_POST['bank_id']) and !empty($_POST['bank_id']))
{
if ($iDEAL->createPayment($_POST['bank_id'], $amount, $description, $return_url, $report_url))
{
header("Location: " . $iDEAL->getBankURL());
exit;
} else {
echo $iDEAL->getErrorMessage();
}
}
}
例如第 28 行的错误
但我不想只修复一段代码,我想知道它是如何工作的。
