I am building a slot machine and am trying to create a shop where you can buy images to replace the text. If I click the button it just resets my money to zero and doesn't replace any text with images. How can I fix this without compromising any functionality or adding hundreds of lines of code?
<html
<?php
//shop
if (isset($_POST['shop']))
{
if ($credit = 50 or $credit > 50)
{
$credit = $credit - 50;
strtr($str, array(
'Zero' => "<img src=img/Zero.png />",
'Bar' => "<img src=img/Bar.png />",
'Double Bar' => "<img src=img/DoubleBar.png />",
'Triple Bar' => "<img src=img/TripleBar.png />",
'Cherry' => "<img src=img/Cherry.png />",
'Seven' => "<img src=img/Seven.png />",
'Diamond' => "<img src=img/Diamond.png />",
'Clover' => "<img src=img/Clover.png />",
));
}
else
{
$message = "You don't have enough money!";
}
}
<!-- display -->
<?php if (!$bust) { ?>
<div id="slots">
<?=join(' | ', $slot_result)?>
</div>
<br/>
<br/>
<?=$message?>
<?php } else { ?>
<?=$message?>
<?php } ?>
<br/>
<br/>
Total cash: €<?=$credit?>
<form method='post'>
<input type='submit' name='spin' value='Spin' />
<input type='hidden' name='credit' value='<?php echo $credit; ?>' />
<input type='submit' name='reset' value='Reset' />
<br>
<br>
<input type='submit' name='shop' value='Change Style - €50' />
</form>

So I'm currently working on a little project that allows a user to input a number into a textbox, after clicking a button that says "add" it should store that value into an array and then allow the user to input another value into that array. There is also a button on the page when the user is finished and wants to sum the values called "Submit". The problem I'm running into is everytime the form posts back, it recreates a new blank array. Any tips?
See the code below:
<html>
<head>
</head>
<body>
<h2>Please Select your title and name:</h2>
<form action='<?php echo $_SERVER["PHP_SELF"]; ?>' method='post'>
<p>
<label for="strFirstname">Type number to add: </label>
<input type='text' name='strNumber' id='strNumber'/>
</p>
<p>
<input type='submit' name='submit' value='Add' />
</p>
<p>
<input type='submit' name='calculate' value='Compute' />
</p>
<?php
$array = array();
if (isset($_POST['submit']))
$num = $_POST['strNumber'];
$array[] = $num;
foreach($array as $num)
echo $num . ' + ';
if(isset($_POST['calculate']))
foreach($array as $num)
echo $num . ' + ';
?>
</form>
</body>
</html>
<?php
session_start();
?>
<html>
<head>
</head>
<body>
<h2>Please Select your title and name:</h2>
<form action='' method='post'>
<p>
<label for="strFirstname">Type number to add: </label>
<input type='text' name='strNumber' id='strNumber'/>
</p>
<p>
<input type='submit' name='submit' value='Add' />
</p>
<p>
<input type='submit' name='calculate' value='Compute' />
<input type='submit' name='clear' value='clear' />
</p>
<?php
if (isset($_POST['submit'])) {
if(!array_key_exists("numbers", $_SESSION)) {
$_SESSION["numbers"] = array();
}
array_push($_SESSION["numbers"], $_POST["strNumber"]);
}
if(isset($_POST['clear'])) {
$_SESSION["numbers"] = array();
}
if(array_key_exists("numbers", $_SESSION)) {
echo implode("+", $_SESSION["numbers"]);
}
if(isset($_POST['calculate'])) {
if(array_key_exists("numbers", $_SESSION)) {
$expression = implode("+", $_SESSION["numbers"]);
eval( '$result = (' . $expression . ');' );
echo "=" . $result;
}
}
?>
</form>
</body>
</html>
Start a session
When the action is "submit"
Check if the session which will store the numbers is initialized
If it's not initialize it as an array
Finally push the number into the array
Check if there is a session initialized if there is print all the numbers ( you can use implode to do that)
if the action is calculate .. just make the calculation ( check eval function )
I have 3 forms with 3 radios each but executed one at a time because of random generator. If I click a radio, it will go to next page and will be checked by the if else statement. Now my problem is, when it gets answered and it's correct, it will output yes. However, my other if else statement of my other radio executes. Since it's not answered, it assumed that it was wrong, so it outputted no.
here's my code:

Here is a cleaner way to do it. Inside is_correct function, it check if particular answer exist in $_POST, if so it returns if the answer is correct:
function is_correct()
{
$answer = array(
'answerOne' => 'A',
'answer2' => 'B',
'answer3' => 'C',
);
foreach ($answer as $k => $v) {
if (array_key_exists($k, $_POST)) {
return $v == $_POST[$k];
}
}
return false;
}
if (is_correct()) {
echo "yes";
} else {
echo "no";
}
I want to give the users of my website the ability to add, edit and remove questions of a FAQ that's stored on a database. They select the title from a form and then they can press 'select' (to edit the q&a) or 'delete'. Deleting doesn't work.
The first problem is: when they click delete, it leads them to the 'edit' form instead of deleting the database table row.
The second problem: when I make them click the button, I ask to confirm the delete. Whether they press 'Ok' or 'Cancel' doesn't matter, they are always lead to the 'edit' form.
The code in the admin panel (index.php):
if(isset($_POST['actie']) && $_POST['actie'] != "")
{
$actie = $_POST['actie'];
if($actie == "csd_faq") { verwerk_csd_faq($DB); }
if($actie == "csd_faq_edit") { verwerk_edit_csd_faq($DB); }
}
if($GLOBALS['logged_in'] && isset($_GET['actie']) && $_GET['actie'] != "")
{
$actie = $_GET['actie'];
if($actie == "csd_faq") { toon_csd_faq($DB); }
if($actie == "csd_faq_edit") { edit_csd_faq($DB); }
}
The code for the functions:
//ADD FAQ
function toon_csd_faq($DB)

You probably want to check for $_POST['delete'] and $_POST['faq_id'], not $_GET['delete'] and $_GET['faq_id'] as the method of the form is POST.
i have a problem here,so here's my code
<div id="educmaininfo">
<?php
foreach($cv->getEducation($_GET['cvid']) as $r){
echo "<a href='#' id='editeducation'>Edit</a> | ";
echo "<input type='hidden' name='cvid' value='".$r['ResumeID']."' />";
echo "<input type='hidden' name='educid' value='".$r['EducationID']."'/>";
echo "<a href='#' id='deleteeducation'>Delete</a><br />";
echo "Date From = ".$r['DateFrom']."<br />";
echo "Date To = ".$r['DateTo']."<br />";
echo "Title =".$r['Title']."<br />";
echo "Summary =".$r['Summary']."<br />";
echo "Place Organization =".$r['PlaceOrganization']."<br />";
echo "Emphasis of Study =".$r['EmphasisOfStudy']."<br />";
echo "Study Details =".$r['StudyDetails']."<br />";
echo "Qualifications =".$r['Qualifications']."<br /><br />";
}
?>
</div>
as you can see that code above, I added 2 hidden stuff, the cvid and the educid.
my question is, how to load this form below
<div id="educajaxinfo" style="display:none">
<table>
<form id="educdetails" method="post" action="">
<input type="hidden" name="cvid" id="cvid" value="<?php echo $v['ResumeID']; ?>" />
<tr><td>Date From:</td><td><input type="text" name="datefromeduc" id="datefromeduc" value="" /></td></tr>
<tr><td>Date To:</td><td><input type="text" name="datetoeduc" id="datetoeduc" value="" /></td></tr>
<tr><td>Title:</td><td><input type="text" name="titleeduc" id="titleeduc" value="" /></td></tr>
<tr><td>Summary:</td><td><textarea name="summaryeduc" id="summaryeduc" rows="10" cols="50"></textarea></td></tr>
<tr><td>Place Organization:</td><td><input type="text" name="pog" id="pog" value="" /></td></tr>
<tr><td>Emphasis of study:</td><td><input type="text" name="eos" id="eos" value=""></td></tr>
<tr><td>Study Details:</td><td><textarea name="studyeduc" id="studyeduc" rows="10" cols="50" ></textarea></td></tr>
<tr><td>Qualifications:</td><td><textarea name="qualificationseduc" id="qualificationseduc" rows="10" cols="50"></textarea></td></tr>
<tr><td><input type="submit" name="update" value="<?php if($count < 3){ echo 'Add';}else{ echo 'Update';}?>" /></td></tr>
</form>
</table>
</div>
with the existing data from the db table, that matches the cvid and educid ?
the flow goes like this, if user clicks the edit link, it should redirect him to the
form with the values loaded in the input forms...if in pure php i can do this by just
doing something like
e.g edit.php?cvid=cvid&educid=educid
how to do it in ajax way?
Use jQuery to call a PHP script that returns JSON encoded data. Then use the “success” callback function to inject the data into your form.
Use the jquery function like following
a href='#' onClick=test
(echo $cvid ,echo $educid ) id='editeducation'>Edit
function test(cvid,educid)
{
jQuery.post('edit.php?cvid=cvid&educid=educid',function(response){
jQuery('#educajaxinfo').html(response);
});
}
include the appropriate jquery min file to use above function.
on edit.php get the two id's and prepare a whole html then it will be shown in #educajaxinfo div
