I've put together the form below that allows a user to retrieve database records from the date they select from a drop down menu.
<html>
<head>
<script type="text/javascript">
function ajaxFunction(name)
{
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer")
{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
else
{// code for IE6, IE5
xmlhttp=new XMLHttpRequest();
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("my_div").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","getrecords.php?dateoftrip="+name,true);
xmlhttp.send();
}
function getquerystring() {
var form = document.forms['frm1'];
var word = form.word.value;
qstr = 'w=' + escape(word); // NOTE: no '?' before querystring
return qstr;
}
</script>
<style type="text/css">
<!--
.style1 {
font-family: Calibri;
font-size: 14px;
}
-->
</style>
</head>
<body>
<form action="getrecords.php" method="get" name="frm1">
<table width="148" border="0">
<tr>
<td width="152"><p class="style1">Select a date from below</p>
<div align="center">
<?php
include("db.php");
$query="select * from finds group by dateoftrip";
echo '<select onchange="ajaxFunction(this.value)">';
$result=mysql_query($query);
while($rows=mysql_fetch_array($result)){
echo "<option name='name' value=".$rows['dateoftrip'].">".$rows['dateoftrip']."</option>";
}
echo "</select>";
?>
</div></td>
</tr>
</table>
</form>
<div id="my_div"></div>
</body>
</html>
and this is the php script which retrieves the records.
<?php
include("db.php");
$dateoftrip= $_GET['dateoftrip'];
$findname= $_GET['findname'];
$finddescription= $_GET['finddescription'];
$query="select * from finds where dateoftrip='$dateoftrip'";
echo "<table>";
$result=mysql_query($query);
while($rows=mysql_fetch_array($result)){
echo "<tr>";
echo "<td>Find Name : </td>";
echo "<td>".$rows['findname']."</td>";
echo "</tr>";
echo "<tr>";
echo "<td>Find Description : </td>";
echo "<td>".$rows['finddescription']."</td>";
echo "</tr>";
}
echo "</table>";
?>
I'd like to extend the functionality a little if at all possible, by adding a 'All Records' option to the drop down menu which obviously returns all the records for the current user.
I've been searching for this for a few days now, and I haven't found an example where there is this added functionality.
I just wondered whether someone could perhaps provide some guidance on how I may go abut this please.

Create an option for the 'ALL' thing
echo '<select onchange="ajaxFunction(this.value)"><OPTION name="name" value="ALLRECORDS">All Records</option>';
Handle your query for the 'ALL' thing
if ($dateoftrip=="ALLRECORDS") {
$query="select * from finds";
} else {
$query="select * from finds where dateoftrip='$dateoftrip'";
}
On a side note you should look about SQL Injection, not using the '*' selector but typing the explicit name of attributes you search

I'm writing some PHP to query from a MySQL database that I have setup on my WAMP server. I'm also learning PHP and html javascript as I go, so the syntax of both languages is still a little unfamiliar to me.
I am running two files through my server, front.php and back.php. front.php contains a selector form where the user may choose a filter to be applied to the php query to MySQL. back.php receives the selection with $_REQUEST and uses that in a SELECT query to MySQL. I have posted the code relating to the selector form in front.php below.
I receive an "Undefined index: family" error when I compile.
As well, I have included both the front.php and back.php files for reference.
I appreciate any help greatly!
<form method="POST">
<select name="family" onchange="showUser (this.value)">
<option value="empty">Select a Family:</option>
<option value="capacitor">capacitor</option>
<option value="resistor">resistor</option>
<option value="ferrite bead">ferrite bead</option>
</select>
</form>
Here is the $_REQUEST call that receives the above choice in back.php
$sql="SELECT * FROM testv2 WHERE family='".$_REQUEST['family']."'";
$result = mysqli_query($con,$sql);

Good Day!
I have a dropdown menu which select employee number and shows table data on basis of that particular selection. I have save as pdf code which saves table data in pdf. It is working fine but my table column headers are only shown not the values.
I have dropdown in one file having javascript which is sent to another file where my table is shown.
Below is the code for my all files and what I have tried for this so far.

The files i.e. practoce.php and pdf libraries are not added becuase they are just creating tables in defined formats
You are mixing up GET and POST. Try one (or both) of the following:
1) In the dropdown code, replace <form> with:
<form method="POST">
2) In the table generation code, read the value back with:
$emp_id =($_REQUEST['employeenumber']);
and also:
if (isset($_REQUEST['submit'])){
To add to your problems, in the first version of search_empnumber.php you posted, you read back $emp_id =($_REQUEST['emp_id']); when the posted value will actually be in $_REQUEST['employeenumber'].
I don't know which part is going wrong for you, but there's some strange things going on in that dropdown code:
<select name="employeenumber" class="input" onchange="showUser(this.value)">
<option value="">Please Select Employee Number:</option>
</div> <!-- ISSUE: Closed a div which was never opened. You're lucky the select box even shows anything-->
<?php
$select_emp="SELECT distinct(emp_number) FROM employees";
$run_emp=mysql_query($select_emp);
//ISSUE: You loop through a lot of data, but then do nothing with it. With every pass of the loop, you simply change the variables, and nothing else. I think you meant to move your <option> into the loop
while($row=mysql_fetch_array($run_emp)){
//ISSUE: You only selected 'emp_number' in your query. Most of these array keys are never filled
$emp_id=$row['emp_id'];
$first_name=$row['first_name'];
$last_name=$row['last_name'];
$emp_number=$row['emp_number']; //This is the only one filled
$total_printers=$row['total_printers'];
$total_scanners=$row['total_scanners'];
$total_pc=$row['total_pc'];
$total_phones=$row['total_phones'];
$other_equips=$row['other_equips'];
?>
<!--ISSUE: Only the last $emp_number from the query is filled. The rest you kept overwriting in your loop-->
<option value="<?php echo $emp_number;?>"><?php echo $emp_number;?></option>
<?php } ?>
</select>
i have a drop down list populated from a database(it is the first cell in a table row) then based on that selection i want it to populate the rest of the row from the same database, each cell is a different table in the database, so far i only have it populating the first cell (calories), i can't figure out how to get it to populate the rest of the cells, thanks

Okay, in this same page your going to have to use some javascript so you can be capable of working on AJAX.
So here's the code for the first page:
<html>
<head>
<script>
function showUser(str) {
if (str == "") {
document.getElementById("para").innerHTML = "";
return;
} else {
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else {
// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("para").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
}
</script>
</head>
<body>
<form>
<select name="test" onchange="showUser(this.value)">

I have a page that has a form on it, when I click a button on the page it sends 3 variables to a layer(page_ref, template_ref, and box_id) via a javascript call.
Then with ajax I get some content from the mysql db with the variables and insert this into a text area on the layer.
The layer has a save button and when I click that I want to save the content of the textarea back to the db.
I can fill the textarea from the db no problem but am having problems pushing is back to the db.
The problem I have is sending the javascript variables to the ajax update page as they need to be passed to php varriables.
heres what I have
on the main page I call a javascript function
edit_box('show',i,'<? echo $page_ref; ?>','<? echo $template_ref; ?>');
in the layer I have this
<style type="text/css">
#popupbox

padding:0;
width: 99%;
height: auto;
margin: 0px auto;
position:absolute;
background: #FBFBF0;

function edit_box(showhide,box_id,page_ref,template_ref)

</script>
<div id="popupbox">
<form id="myForm" action="update_textarea.php" method="post">
<input type="hidden" name="page_ref" value="<? echo $page_ref; ?>" />
<input type="hidden" name="template_ref" value="<? echo $template_ref; ?>" />
<input type="hidden" name="box_id" value="<? echo $box_id; ?>" />
<textarea name="edit_content" id="edit_content" style="width: 500px; height:500px;"></textarea>
<center>close</center>
<button id="sub">Save</button>
</form>
</div>
then I have get_contents page
<?php
include("connect.php");
$page_ref = $_GET['page_ref'];
$template_ref = $_GET['template_ref'];
$box_id = $_GET['box_id'];
$sql = "SELECT * FROM site_content WHERE page_ref='$page_ref' AND template_ref='$template_ref' AND box_id='$box_id' AND box_type='text'";
$result = mysql_query($sql);
while($row=mysql_fetch_array($result))
{
echo "<p>".$row['content']."</p>";
}
?>
and finally the update_textarea page
<?
include("connect.php");
$page_ref = $_POST['page_ref'];
$template_ref = $_POST['template_ref'];
$box_id = $_POST['box_id'];
$edit_content = $_POST['edit_content'];
if(mysql_query("UPADTE site_content SET content='$edit_content' WHERE page_ref='$page_ref' AND template_ref='$template_ref' AND box_id='$box_id' AND box_type='text'"))
{
echo "Successfully Inserted";
}
else
{
echo "Insertion Failed";
}
?>
I realised that i needed to set the values of the hidden inputs in the ajax call after
document.getElementById("edit_content").innerHTML=xmlhttp.responseText;
by adding
document.getElementById("box_id").value = box_id;
etc
