我有这样的HTML:
<?php
if(isset($_POST['do_change'])) {
// that is the place where i need to place if(changes have been made in input)
echo "yeey y made changes";
}
?>
<form action="changes.php" method="POST">
<input type="text" name="goose">
<input type="text" name="cat">
<input type="submit" name="do_change">
</form>null
我需要和显示文本:“您在输入中使用名称goose编写了一些东西，而使用名称cat编写了什么东西”
要检查用户是否填写了多个文本输入字段，例如，您可以执行以下操作:
// array with names of the fields you want to check
$fieldnames = ['goose', 'cat', 'kangaroo'];
// initialize counter of filled fields with 0
$filled = 0;
// loop over the field names
foreach($fieldnames as $fieldname) {
// check if a value under that name exists in the $_POST array,
// and if so, that its value is not the empty string
if(isset($_POST[$fieldname]) && $_POST[$fieldname] !== '') {
$filled++;
}
}
if($filled > 1) {
echo 'You filled more than one field.';
}
您忘了{}
第一页:
<form action="changes.php" method="POST">
<input type="text" name="goose">
<input type="submit" name="do_change">
</form>
changes.php:
if(isset($_POST['do_change'])){
// that is the place where i need to place if(changes have been made in input)
echo "yeey y made changes";
}
