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);
FRONT.PHP

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.
For Dropdown:

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>
After advice taken from the community i started work on a AJAX/php script to retrieve data based on a variable from a MySQL database. It works reasonably well now i'd like to be able to click on any of the variables that are shown and that take you to another page whilst remembering your selection. Is this possible?
Here is a link to my website.
Here is my PokemonFight.php code:

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("txtHint").innerHTML = xmlhttp.responseText;
}
};
xmlhttp.open("GET","getpokemon.php?q="+str,true);

The folowing piece of code was what i wasn't understanding but replacing what i previously with this new piece of code added a hyperlink on the Pokemon name which links to another page that i'm creating with an ID value of the PokedexID. Hope this helps anyone that was as stuck as i was.
Before Code:
echo "<td>" . $row['PokedexID'] . "</td>";
After Code:
echo "<td><a href=' viewpokemon.php?PokedexID=" . $row["PokedexID"] . "'>" . $row["Pokemon_Name"] . "</a></td>"
I am using ajax to fetch information for my database and im running into a problem. nothing is being shown in return.
I have a select list that calls for a js script to run onchange, that calls for the php file to get the database information and return it in a table.
the problem is that upon the onchange event, I have a table show up with just the table heads but no information below. I checked console and the error Im getting is this:
GET http://lineofcode.com/favicon.ico 401 (Unauthorized)
thats the only error that shows. What am i doing wrong? why is my table blank?

Just an observation but shouldn`t code be like this ?

xmlhttp.send();
xmlhttp.onreadystatechange = function() {

document.getElementById("teamInfo").innerHTML = xmlhttp.responseText;
}
};
Also try to print_r($_GET) to see if the value is being posted
Not sure if this is the problem but you are using intval() --e.g. for converting input string to integers --and your teamnames in your database won't match that (assuming you've given your teams names and not numbers).
I have a select input having several options in it as html and I want to execute a query on the basis of a selected value in the dropdown list.
<select name="test">
<option value="apple">apple</option>
<option value="banana">banana</option>
<option value="mango">mango</option>
</select>
I want to execute the following query with a criterion value selected in the above drop down list.
<?php $sql=mysqli_query($con,"select * from tblsession where sessionid='".$_REQUEST['test']."'"); ?>
pls help.
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)">
<option value="Apple">Apple</option>
<option value="Bannana">Bannana</option>
<option value="Bannana">Mango</option>
</select>
</form>
<br>
<div id="para"><b>What you will excute will be listed here...</b></div>
</body>
</html>
And this is getuser.php
<!DOCTYPE html>
<html>
<head>
<style>
table {
width: 100%;
border-collapse: collapse;
}
table, td, th {
border: 1px solid black;
padding: 5px;
}
th {text-align: left;}
</style>
</head>
<body>
<?php
$q = intval($_GET['q']);
$con = mysqli_connect('host','username','password','db');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
mysqli_select_db($con,"db");
$sql="SELECT * FROM test WHERE id = '".$q."'";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['apple'] . "</td>";
echo "<td>" . $row['bannana'] . "</td>";
echo "<td>" . $row['mango'] . "</td>";
}
mysqli_close($con);
?>
</body>
</html>
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.
Amended Form Code
<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)"><OPTION name="name" value="ALLRECORDS">';
$result=mysql_query($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>
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
