从for循环插入-将选择选项值仅添加到一条记录

[英]Insert from for loop - add select option value to only one record

问题描述

我在for循环中发生插入，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的选择菜单中获取值，该值包含在变量$ action中。 该菜单仅针对表单上的一条记录出现，具体取决于用户的选择。

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：

浏览完代码后，发现所有四个文本框均已打开，并且用户将文本插入这四个框中的任何一个。

要解决此问题，请执行以下操作： 

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

另一种方法是在提供复选框之前，以便使用者可以选择发送邮件的选项。

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.";
}
}
