这是一个简单的表单包含多个复选框选项和textarea输入:
<form method="post" name="form1" action="<?php echo $editFormAction; ?>">
<table>
<tr><th colspan="2">BREATHING CIRCULATION</th></tr>
<tr><th>#</th><th>Instruction Name</th></tr>
<tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Respirations normal rate"></td><td>Respirations normal rate</td></tr>
<tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Respirations effort normal"></td><td>Respirations effort normal</td></tr>
<tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Breath Sounds-normal"></td><td>Breath Sounds-normal</td></tr>
<tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Skin colour-normal"></td><td>Skin colour-normal</td></tr>
<tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Heart rhythm & rate normal"></td><td>Heart rhythm & rate normal </td></tr>
<tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="No Oedema"></td><td>No Oedema </td></tr>
</table>
<textarea name="InstrCheck[]" id="InstrCheck" placeholder="set your own instruction"> </textarea>
<input type="hidden" name="MM_insert" value="form1">
<input type="hidden" value="<?php echo $_GET['a'];?>" name="pat_id">
</form>
我的问题是如何插入已检查的选项(可能多于一个)和textarea值(如果输入)并将所有这些输入值插入到DB中的相同列中,但每个输入都在“单独的行”中。我尝试了这段代码,但没有插入任何东西(空单元格):
<?php
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
$pat_id = $_GET['a'];
$Date = date("d-m-Y");
$Time = date("H:i:s");
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
foreach ($_POST['InstrCheck'] as $value) {
$insertSQL = "INSERT INTO instruction (instName, instTime, instDate, pat_id) VALUES ('$value', '$Time', '$Date', '$pat_id')";
}
mysql_select_db($database_PPS, $PPS);
$Result1 = mysql_query($insertSQL, $PPS) or die(mysql_error());
$insertGoTo = "Patint_selection.php?a=$pat_id";
if (isset($_SERVER['QUERY_STRING'])) {
$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
$insertGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $insertGoTo));
}
?>

如果我说对了你的话:
IF(isset($_POST['InstrCheck']) && isset($_POST['comment'])) {
$checked = $_POST['InstrCheck'];
$comment= $_POST['comment'];
IF(!empty($checked) && is_array($checked)) {
foreach($checked as $check) {
$query = 'INSERT INTO table (checkedID, comment) VALUES (\''.mysql_real_escape_string($check).'\', \''.mysql_real_escape_string($comment).'\'';
mysql_query($query);
}
}
}
您可以根据自己的喜好编辑查询,这只是将多行插入数据库的快捷方式。
修改:我误读了您的第一个HTML表单,您应该将 textarea 的名称编辑为其他内容,然后编辑InstrCheck[]
并进行修改相反,comment
,您可以使用上面给出的示例。

您可以使用此HTML表单...
<form method="post" name="form1" action="<?php echo $editFormAction; ?>">
<table>
<thead>
<tr><th colspan="2">BREATHING CIRCULATION</th></tr>
<tr><th>#</th><th>Instruction Name</th></tr>
</thead>
<tbody>
<tr><td><input name="InstrCheck0" type="checkbox" id="InstrCheck0" value="Respirations normal rate" /></td><td>Respirations normal rate</td></tr>
<tr><td><input name="InstrCheck1" type="checkbox" id="InstrCheck1" value="Respirations effort normal" /></td><td>Respirations effort normal</td></tr>
<tr><td><input name="InstrCheck2" type="checkbox" id="InstrCheck2" value="Breath Sounds-normal" /></td><td>Breath Sounds-normal</td></tr>
<tr><td><input name="InstrCheck3" type="checkbox" id="InstrCheck3" value="Skin colour-normal" /></td><td>Skin colour-normal</td></tr>
<tr><td><input name="InstrCheck4" type="checkbox" id="InstrCheck4" value="Heart rhythm & rate normal" /></td><td>Heart rhythm & rate normal </td></tr>
<tr><td><input name="InstrCheck5" type="checkbox" id="InstrCheck5" value="No Oedema" /></td><td>No Oedema </td></tr>
</tbody>
</table>
<textarea name="InstrCheck6" id="InstrCheck6" placeholder="set your own instruction"></textarea>
<input type="hidden" name="MM_insert" value="form1" />
<input type="hidden" name="pat_id" value="<?php echo $_GET['a']; ?>" />
</form>
...并使用此PHP脚本对待它:
<?php
$Date = date("d-m-Y");
$Time = date("H:i:s");
// Has the form been sent?
if (isset($_POST["MM_insert"])) {
// We can't test what's in $_POST["MM_insert"] before we even know it exists
if ($_POST["MM_insert"] == "form1")
{
// ONE connection to the database is enough; it shouldn't be in a for or foreach loop
mysql_select_db($database_PPS, $PPS);
// The pattern's id is stored in the pat_id hidden field, right?
$pat_id = $_POST["pat_id"];
// Never trust user input!
$pat_id = mysql_real_escape_string($pat_id);
// Checkboxes & textarea have name attributes going from 0 to 6 (see HTML code)
for ($i = 0 ; $i < 7 ; $i++)
{
// Is the number $i checkbox checked?
if (isset($_POST["InstrCheck$i"]))
{
// Let's get its value
$value = $_POST["InstrCheck$i"];
// Again... never trust user input.
$value = mysql_real_escape_string($value);
// Insert data
mysql_query("
INSERT INTO instruction (instName, instTime, instDate, pat_id)
VALUES ('$value', '$Time', '$Date', '$pat_id')
");
}
}
}
}
?>

保存到数据库的空单元格是textarea
中的值。
您的代码仅保存textarea
的原因是因为它是mysql_query
执行的唯一查询。您的foreach
循环会覆盖每个查询,$insertSQL
的最后一个值是textarea查询。因此,要解决此问题,您必须在mysql_query
循环内移动foreach
并在循环开始之前连接到数据库。
/**
* Moving the mysql_query inside the loop requires you connect to the database
* before the loop starts
*/
mysql_select_db($database_PPS, $PPS);
/** Move your mysql_query inside your foreach loop **/
foreach ($_POST['InstrCheck'] as $value) {
$insertSQL = "INSERT INTO instruction (instName, instTime, instDate, pat_id) VALUES ('$value', '$Time', '$Date', '$pat_id')";
// Moved inside the loop...now this will run for each loop
$Result1 = mysql_query($insertSQL, $PPS) or die(mysql_error());
}
其他答案同样好,并指出了一些值得考虑的事情。我只是想让你了解原始代码错误的原因。
