I have a program which appends an input(type="hidden") using jquery, to an
html so that when I click the submit button, it passes the value to a php file
and I can process it. However, it seems that the hidden type is not really being appended to the
html nor it is being passed to the php file. I already used method="get" to see the values in the address bar
and print_r to see the values being catched but there's nothing. To check if my form is actually passing a value, I added a
<input type="hidden" name="absent[]" value="testing" />
in the
HTML and the value got passed but the ones in the jquery aren't.
Here are my files:
jquery:
$(function(){
$("td").click(function(){
if($(this).hasClass("on"))
{
alert("Already marked absent");
}
else
{
$(this).addClass("on");
var currentCellText = $(this).text();
var temp = $(this).attr('id');
$("#collect").append("<input type='hidden' name='absent[]' value = '" + temp + "'/>" + currentCellText);
alert(temp);
}
});
$("#clicky").click(function(){
$("td").removeClass("on");
$("#collect").text('');
$("#collect").append("Absentees: <br>")
alert(temp);
});
});
Here is the
html part:
<?php
session_start();
include 'connectdb.php';
$classID = $_SESSION['csID'];
$classQry = "SELECT e.csID, c.subjCode, c.section, b.subj_name, e.studentID, CONCAT(s.lname, ', ' , s.fname)name
FROM ENROLLMENT e, CLASS_SCHEDULE c, STUDENT s, SUBJECT b
WHERE e.csID = c.csID
AND c.csID = '" . $classID . "'
AND c.subjCode = b.subjCode
AND e.studentID = s.studentID
ORDER BY e.sort;";
$doClassQry = mysql_query($classQry);
echo "<table id='tableone'>";
while($x = mysql_fetch_array($doClassQry))
{
$subject = $x['subj_name'];
$subjCode = $x['subjCode'];
$section = $x['section'];
$studentArr[] = $x['name'];
$studentID[] = $x['studentID'];
}
echo "<thead>";
echo "<tr><th colspan = 7>" . "This is your class: " . $subjCode . " " . $section . " : " . $subject . "</th></tr>";
echo "</thead>";
echo "<tbody>";
echo "<tr>";
for($i = 0; $i < mysql_num_rows($doClassQry); $i++)
{
if($i % 7 == 0)
{
echo "</tr><tr><td id = '". $studentID[$i] . " '>" . $studentArr[$i] . "</td>";
}
else
{
echo "<td id = '". $studentID[$i] . " '>" . $studentArr[$i] . "</td>";
}
}
echo "</tr>";
echo "</tbody>";
echo "</table>";
?>
Here's the
html part with the form:
<form name="save" action="saveTest.php" method="post">
<div id="submitt">
<input type="hidden" name="absent[]" value="testing"/>
<input type="submit" value="submit"/>
</div>
</form>
And here's the php part which processes the form (saveTest.php):
<?php
$absent = $_POST['absent'];
//echo "absnt" . $absent[] . "<br>";
echo count($absent) . "<br>";
//print_r($_POST) . "<br>";
?>
