我正在尝试使用php和mysql对表单进行多个产品添加,我对这样做的概念感到困惑,
我期望的输出是,提供一个表格,其中至少有十行多个字段需要填写并在这些表格中进行验证,如果没有错误则继续插入。
到目前为止,这是我对单个表单插入的理解:
$add_errors = array();
//if there is a post request
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
// do some validation
if (empty($_POST['name'])) {
$add_errors['name'] = 'Please enter the name!';
}
if (empty($_POST['description'])) {
$add_errors['description'] = 'Please enter the description!';
}
if (empty($add_errors)) { // If everything's OK.
//do the insertion
$q = 'INSERT INTO ........')';
}
}//end of form submission
echo '<form action="product_add.php" enctype="multipart/form-data" method="post" accept-charset="utf-8">';
echo '<input type=..... name=...... id=.....>';
echo '<input type=..... name=...... id=.....>';
echo '<input type=..... name=...... id=.....>';
echo '</form';
//this form is only a single row with multiple column(field) ,I am trying to make it into multiple column
答案 0 :(得分:1)
我会重写上面的代码......我将在这里重写它:
<?php
$rows = 10; // rows desired.
//if there is a post request
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
while($i < $rows){
if (empty($_POST['description'.$i])) {
$add_errors['description'.$i] = 'Please enter the description!';
}
// more error checking if needed...
++$i;
}
if (empty($add_errors)) { // If everything's OK.
//do the insertion
$q = 'INSERT INTO ........')';
}
}//end of form submission
echo '<form action="product_add.php" enctype="multipart/form-data" method="post" accept-charset="utf-8">';
$i = 0;
while($i < $rows){
echo '<input type=..... name="description'.$i.'" id=.....>';
++$i;
}
echo '</form';
?>
尝试类似的东西...(我的代码可能有一两个错误,因为我刚刚在这里写了它并没有测试它)但这是一般的想法。 =)
