正在创建一个表，其中添加了每个产品/品牌/条件/数量，并发送到我的电子邮件中。但是，如果其中一个为空，则会破坏表格式。我尝试过if/else语句，isset/！空的，还有我能想到的任何其他东西。如果留空，我想添加要插入的空白列/行。
- 由于我对每个添加的项目都使用计数器（product_1，product_2），并且没有限制，所以我使用strpos来查找并"快速"添加到表中
--我无法附上照片，因为这是我的第一篇帖子。——
这是我现在拥有的，在没有字段为空时效果很好：
$content .= "<table rules='all' style='border-color: #666; width: 800px; border: 1px solid black; border-collapse: collapse; margin: 0 auto;'>'r'n";
foreach($_POST as $key => $value) {
$partqty = strpos($key, 'Part_Quantity');
$partcond = strpos($key, 'Part_Condition');
$partbrand = strpos($key, 'Part_Brand');
$partmodel = strpos($key, 'Part_Model');
if ($partqty === 0) {
$content .= "<tr>'r'n";
$content .= " <td style='width:15%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
}
if ($partcond === 0) {
$content .= " <td style='width:65%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
}
if ($partbrand === 0) {
$content .= " <td style='width:10%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
}
if ($partmodel === 0) {
$content .= " <td style='width:10%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
$content .= "</tr>'r'n";
}
}
$content .= "</table>'r'n";
这是我想做但不起作用的想法
foreach($_POST as $key => $value) {
$partqty = strpos($key, 'Part_Quantity');
$partcond = strpos($key, 'Part_Condition');
$partbrand = strpos($key, 'Part_Brand');
$partmodel = strpos($key, 'Part_Model');
if ($partqty === 0) {
$content .= "<tr>'r'n";
$content .= " <td style='width:15%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
}
if ($partqty === false) {
$content .= "<tr>'r'n";
$content .= " <td style='width:15%;'><input value='empty' style='border: none; width:100%;'></td>'r'n";
}
if ($partcond === 0) {
$content .= " <td style='width:65%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
}
if ($partcond === false) {
$content .= " <td style='width:65%;'><input value='empty' style='border: none; width:100%;'></td>'r'n";
}
if ($partbrand === 0) {
$content .= " <td style='width:10%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
}
if ($partbrand === false) {
$content .= " <td style='width:10%;'><input value='empty' style='border: none; width:100%;'></td>'r'n";
}
if ($partmodel === 0) {
$content .= " <td style='width:10%;'><input value='" . $value . "' style='border: none; width:100%;'></td>'r'n";
$content .= "</tr>'r'n";
}
if ($partmodel === false) {
$content .= " <td style='width:10%;'><input value='empty' style='border: none; width:100%;'></td>'r'n";
$content .= "</tr>'r'n";
}
}
打印示例：
Array (
[Part_Quantity_1] => 1
[Part_Condition_1] => New
[Part_Brand_1] => brand1
[Part_Model_1] => model1
[Part_Quantity_2] => 2
[Part_Condition_2] => New
[Part_Brand_2] => 2
[Part_Model_2] => 2
[Estimated_Total] => 0
[Estimated_Hours] => 0
[Name] => JohnDoe
[Email] => test@test.com
[Email_Verify] => test@test.com
[Confirmation] => I agree
[NameID] => form2-name
[EmailID] => form2-email
[HoursID] => form2-hours
[AjaxCall] => form2_ajax
)
试试这个。

不确定预期的输出或发布数据是什么，但这应该有效，但它尚未经过测试。我还注意到你没有在的任何地方输出行的标题
foreach($_POST as $key => $value) {
switch($key) {
case 'Part_Quantity':
$width = "15%";
break;
case 'Part_Condition':
$width = "60%";
break;
default:
$width = "10%";
break;
}
$content = "<tr>";
$content .= "<td style='width:".$width.";'><input value='" . (is_int($value) ? $value : 'empty' . "' style='border: none; width:100%;'></td>";
$content .= "</tr>";
}
