我在 for 循环中发生了插入，将 4 条记录插入数据库。我只想让这些新记录中的一个从表单中的选择菜单中获取值，该菜单包含在变量 $action 中。该菜单仅针对表单上的一条记录显示，具体取决于用户选择。

表结构为：

CREATE TABLE IF NOT EXISTS `pathway` (
  `pathway_pk` int(3) NOT NULL AUTO_INCREMENT,
  `case_fk` int(3) NOT NULL,
  `level` int(1) NOT NULL,
  `pathway_allowed` char(1) NOT NULL DEFAULT 'n',
  `pathway_action_fk` int(2) NOT NULL DEFAULT '0',
  `comment` text NOT NULL,
  `created` datetime NOT NULL,
  `created_by` int(3) NOT NULL,
  `updated` datetime NOT NULL,
  `updated_by` int(3) NOT NULL,
  PRIMARY KEY (`pathway_pk`)
)

PHP：

$author_pk = $_GET['author_pk'];
$case_pk = $_GET['case_pk'];
$patient_pk = $_GET['patient_pk'];

$pathway_allowed = intval($_POST['allowed']);

$action = mysql_real_escape_string($_POST['actions']);


if(isset($_POST['submit'])){ 

$pathway_comment = array();
foreach($_POST['comment'] as $comment) {
    $pathway_comment[]= mysql_real_escape_string($comment);
}
for($i=0, $count = count($pathway_comment);$i<$count;$i++) {
    $comment = $pathway_comment[$i];
    $query = sprintf(
        "INSERT INTO pathway (             
           pathway_pk,
           case_fk,
           level,
           pathway_action_fk,
           pathway_allowed,
           comment
        ) VALUES (
           '',
           '$case_pk',
           '1',
           '$action',
           '%s',
           '$comment')", $pathway_allowed === $i ? 'y' : 'n');

       $result = mysql_query($query, $connection) or die(mysql_error());

其余的部分：

我已经通过使用解决了这个问题

$pathway_allowed = intval($_POST['allowed']);
$action = mysql_real_escape_string($_POST['actions']);


if(isset($_POST['submit'])){ 

$inserted_ids = array();
$pathway_comment = array();

foreach($_POST['comment'] as $comment) {
    $pathway_comment[]= mysql_real_escape_string($comment);
}

for($i=0, $count = count($pathway_comment);$i<$count;$i++) {
    $comment = $pathway_comment[$i];
    $query = sprintf(
        "INSERT INTO pathway (             
           pathway_pk,
           case_fk,
           level,
           pathway_allowed,
           comment
        ) VALUES (
           '',
           '$case_pk',
           '1',
           '%s',
           '$comment')", $pathway_allowed === $i ? 'y' : 'n');

$result = mysql_query($query, $connection) or die(mysql_error());
if ($result) {
$inserted_ids[] = mysql_insert_id();     
 }
}
$query_update = "UPDATE pathway SET pathway_action_fk = '$action' WHERE pathway_pk IN (" . implode(",", $inserted_ids) . ") AND pathway_allowed = 'y'";
$result_update = mysql_query($query_update, $connection) or die(mysql_error());
if($result_update){
$message = "- The pathways for level 1 have been created.";
}
}

浏览完您的代码后，发现所有四个文本框都是打开的，并且用户可以在 4 个框中的任何一个中插入文本。

要解决此使用：

if ( strlen ( trim ( $comment ) ) > 0 )
{
    //use insert query
}

另一种方法是在使用之前提供一个复选框，以便使用可以选择发送东西的选项..
