jquery not sending button choice to php - php

I have a search function that will accept a search string and send it to a php file for parsing a database column. I'd also like users to choose which aspect of the website they'd like to search (comics, artwork, or both). Comic and Artwork or stored in two separate tables.
This is a function that will accept an input search string from the html below and send it to a php file.
<script type="text/javascript">
function search(searchString) {
//var site = $("#site").val();
$.get("./scripts/search.php", {_input : searchString},
function(returned_data) {
$("#output").html(returned_data);
}
);
}
And this is javascript to accept a choice to search "comics", "artwork" or "all".
function searchChoice(choice) {
alert("Choice: " + choice);
$.get("./scripts/search.php", {_choice : choice}
);
}
</script>
HTML:
<!--Search filtering for comics, artwork, or both-->
<span class="search"><b>Search for: </b> </span>
<div class="btn-group" data-toggle="buttons-radio">
<span class="search">
<button type="button" class="btn" id="comics" onclick="searchChoice(this.id)">Comics</button>
<button type="button" class="btn" id="artwork" onclick="searchChoice(this.id)">Artwork</button>
<button type="button" class="btn" id="all" onclick="searchChoice(this.id)">All</button>
</span>
</div>
<br/>
<br/>
<!--Search functionality-->
<span class="search">
<input type="text" onkeyup="search(this.value)" name="input" value="" />
</span>
<br />
<span id="output"><span class="sidebarimages"> </span></span>
PHP excerpt:
$input = (isset($_GET['_input']) ? ($_GET['_input']) : 0);
$siteChoice = (isset($_GET['_choice']) ? ($_GET['_choice']) : "all");
You can see the javascript correctly alerting out "Choice: comics" when comics button is selected, but the php side, echo "</br>Choice: " . $siteChoice;, is echo'ing out "all", which is incorrect.
Any ideas would be greatly appreciated!

As mentioned #E_p, that is the problem ... another option is to create a variable and store the data there ... try this: you don't need change the html
var mySearchString = 0;
var myChoice = 'all';
function search(searchString) {
mySearchString = searchString;
GetSearch();
}
function searchChoice(choice) {
myChoice = choice;
GetSearch();
}
function GetSearch(){
$.get("./scripts/search.php", {_input : mySearchString, _choice : myChoice},
function(returned_data) {
$("#output").html(returned_data);
}
);
}

You do not keep state for _choice.
When search is called it does not pass it to a server.
You need to change buttons to option and in search function pass both. to a server at the same time

Replace the buttons with radio buttons and use form.Serialize()
<form id="searchform">
<input type="radio" name="_choice" value="comics" />Comics<br/>
<input type="radio" name="_choice" value="artwork" />Artwork<br/>
<input type="radio" name="_choice" value="all" />All<br/>
<input type="text" onkeyup="search()" name="_input" value="" />
</form>
Javascript
function search() {
//var site = $("#site").val();
$.get("./scripts/search.php", $('#searchform').serialize(),
function(returned_data) {
$("#output").html(returned_data);
}
);
}
The .serialize() function converts form input to JSON so you don't have to type manually, No more parameter, and no two functions, just one to do them all

PHP form button redirects (is changing the URL) even if I don't want to

So, I have a button in a form.
<form>
<button onclick="alert('<?php echo $value ?>')">Click me!</button>
</form>
$value = "1.png"
When I press it changes the url like this:
Initial:
index.php?id=82
After I click:
index.php?
As you can see, I want the button to only show an alert, not to change the URL
Full code:
<form>
<label>Title</label><br>
<input type="text" value="<?php echo $title ?>"><br><br>
<label>Description</label><br>
<textarea rows="5" maxlength="120"><?php echo $desc ?></textarea><br><br>
<div>
<?php for($k = 0; $k < count($images); $k++) { ?>
<div>
<img src="<?php echo $images[$k] ?>">
<button onclick="alert('<?php echo $images[$k] ?>')">Click me!</button>
</div>
<?php } ?>
</div>
</form>
PS: I'm not sure what's the problem but I think is the form
There are at least two ways of achieving this:
html:
<button type="button" onclick="alert('<?php echo $images[$k] ?>');">Click me</button>
<button onclick="alert('<?php echo $images[$k] ?>');return false;">Click me!</button>
The first option I think would be best if the only thing you want to achieve is to alert a text.
The second option might be better if call a function when you click on the button and want different responses:
<button onclick="return foo('<?php echo $images[$k] ?>');">Click me!</button>
in javascript:
function foo(image) {
//If image is img1 then update the page
//If any other image, don't update the page
if (image == 'img1') {
return true;
}
return false;
}
When you fail to specify the type of a <button> element, the browser will imply that it is a submit type button. Thus, when you press the button, your browser is submitting the form with it.
You should either,
a) Specify a type for the button other then submit, or
b) Return false in the javascript code to run, to prevent the click event from bubbling.

JQuery: event.preventDefault() isn't preventing a refresh

I've been building a mail form that is supposed to pass the information into a php document that handles sanitization and mailing, but I didn't want it to refresh so i decided to use JQuery and AJAX. I'm fairly new to JQuery and haven't used any AJAX before so I am a bit of a rookie when it comes to this...
Even though I have the .submit(function(e){e.preventDefault();}); it still submits the ordinary way and gives an error when it can't find film_mail in the PHP. Which means that it isn't stopping the submit and isn't passing the code to the PHP.
I've tested with alerts and the JQuery works in to the if() but after that some thing goes wrong.
Here is the code that causes the issue (some of the classes and ids are in swedish but that shouldn't cause an error...)
HTML
<div id="film" class="hidden" >
<form id="film_form" action="formular-send.php" method="post">
<input id="film_mail" type="text" name="mail" placeholder="Mail adress">
<input id="film_nr" type="number" name="nr" min="1">
<input id="film_antal" type="number" name="antal" min="1">
<input id="film_namn" type="text" name="namn" placeholder="Namn">
<input id="film_adress" type="text" name="adress" placeholder="Adress">
<input id="film_ort" type="text" name="ort" placeholder="Ort">
<input id="film_postnr" type="text" name="postnr" placeholder="Postnummer">
<textarea id="film_medelande" name="medelande" placeholder="Medelande"></textarea>
<button id="film_submit" type="submit" name="submit">Skicka</button>
<div class="error-mesage" ></div>
</form>
</div>
JQuery
$(document).ready(() => {
var emne = $('#emneid').val();
if (emne == 'film') {
$('#film_form').submit(function(e) {
e.preventDefault();
var mail = $('#film_mail').val();
var nr = $('#film_nr').val();
var antal = $('#film_antal').val();
var namn = $('#film_namn').val();
var adress = $('#film_adress').val();
var ort = $('#film_ort').val();
var postnr = $('#film_postnr').val();
var medelande = $('#film_medelande').val();
var submit = $('#film_submit').val();
$.post('formular-send.php', {
film_mail: mail,
film_nr: nr,
film_antal: antal,
film_namn: namn,
film_adress: adress,
film_ort: ort,
film_postnr: postnr,
film_medelande: medelande,
film_submit: submit,
emne: emne
});
// I heard that .load() had been removed in 3.0 so i tried to use $.post() because I thougt that might work but it sadly didn't...
// but I kept the .load() incase it'd be useful
/*$('#film_form').load('formular-send.php', {
film_mail: mail,
film_nr: nr,
film_antal: antal,
film_namn: namn,
film_adress: adress,
film_ort: ort,
film_postnr: postnr,
film_medelande: medelande,
film_submit: submit,
emne: emne
});*/
});
} else {
}
})
PHP
<?php
$filmmail = $_POST['film_mail'];
?>
If there is anything else that is needed i'd be happy to post it to.
I think $('#emneid').val() returns something different than 'film' and your listener is never attached.
Can you please double check the returned value of $('#emneid').val();
In addition of other comments, I think you need to add the correct name for you button or your PHP form will not work.
<?php
$filmmail = $_POST['film_mail']; //for the moment your need to put $_POST['mail'] because your button is named mail instead of film_mail
?>
Please also take care in production / later use, don't use directly $_POST or your code will be vulnerable from some SQL injection and so on. Take a look at htmlspecialchars function.
Edit :
I think you can just use HTML form and php to post your data, without posting it via JS/Jquery. If you want to have some data validation before sending it, you can just call an event before submit like described in this post : (Validate form before submit jquery)
I think you maybe have a problem with your selector to trigger the function, I don't know the submit function but maybe try with on('submit') or at least it will work with on('click').
$(document).on('click', '#film_submit button[type=submit]', function(e) {
var isValid = $(e.target).parents('form').isValid();
if(!isValid) {
e.preventDefault(); //prevent the default action
}
});
<button> does not have attribute type, but <input> has, try change <button> to <input>
UPD
Where is the tag with id of #emneid?
Try this. Please replace your HTML with my HTML code.
<div id="film" class="hidden" >
<form id="film_form" action="formular-send.php" method="post">
<input id="film_mail" type="text" name="film_mail" placeholder="Mail adress">
<input id="film_nr" type="number" name="film_nr" min="1">
<input id="film_antal" type="number" name="film_antal" min="1">
<input id="film_namn" type="text" name="film_namn" placeholder="Namn">
<input id="film_adress" type="text" name="film_adress" placeholder="Adress">
<input id="film_ort" type="text" name="ort" placeholder="Ort">
<input id="film_postnr" type="text" name="film_ort" placeholder="Postnummer">
<textarea id="film_medelande" name="film_medelande" placeholder="Medelande"></textarea>
<button id="film_submit" type="submit" name="submit">Skicka</button>
<div class="error-mesage" ></div>
</form>
</div>

How to make a div appear from a php variable using jquery

I am populating a list of checkboxes from a foreach loop, and giving each an ID. I have added a set of divs below that would appear, depending on which checkbox is created. I was thinking I could load the id variable into a jQuery if statement, and then use a .toggle to show or hide the corresponding div.
<?php
//Call Programs
$getPrograms = Doctrine::getTable('Program')->createQuery()->where('subsection=?', 'mfa')->orWhere('subsection=?', 'mps')->orWhere('subsection=?', 'mat')->orWhere('subsection=?', 'ma')->orderBy('title ASC')->execute(); ?>
<div class="form_row">
<label>
<span><sup class="required_form_item">*</sup>Select Program</span>
</label>
<div class="buttonColumn" style="margin-left:170px;">
//loop the records in with checkboxes
<?php foreach ($getPrograms as $prog): ?>
<?php
$subsection = $prog->getSubsection();
$subsection = strtoupper($subsection);
$trimProg = trim($prog->getTitle(), ' ');
$removeChars = array(" ", "&");
$trimProg = str_replace( $removeChars, '', $trimProg );
$trimProg = preg_replace('/\s\s+/', '_', $trimProg);
?>
//custin id matches record title
<input type="checkbox" name="program" class="isChecked" id="<?php echo $trimProg; ?>" value="<?php echo $subsection . " " . $prog->getTitle() ?>" /><?php echo $subsection . " " . $prog->getTitle() ?><br />
<?php endforeach ?>
</div>
</div>
The following divs would be set to display:none until the matching checkbox is checked.
<div class="form_row sessionTime" id="Program1" style="display:none;">
Please choose an session time:
<input type="checkbox" name="schedule" value="5:00 pm" />5:00 pm<br />
</div>
<div class="form_row sessionTime" id="program2" style="display:none;">
Please choose an session time:
<input type="checkbox" name="schedule" value="10:00 pm" />10:00 pm<br />
</div>
...
And this is what I thought would work...but alas...it doesn't
$('.isChecked').click( function() {
if ( $(this).is(':checked') ) {
$thisID = $(this).attr("id");
$('.'+ $thisID).show();
}
else {
$('.'+ $thisID).hide();
}
}
);
You should be using "Program1" as class name instead of id like this
<div class="form_row sessionTime Program1" style="display:none;">
Please choose an session time:
<input type="checkbox" name="schedule" value="5:00 pm" />5:00 pm<br />
</div>
And your jQuery code should work, which you can simplify as follows:
$('.isChecked').click( function() {
if ( $(this).is(':checked') ) {
$('.'+ this.id).show();
}
else {
$('.'+ this.id).hide();
}
});
I tested this code # home and it works as you might want
<html>
<head>
<script src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
<script>
$(document).ready(
function()
{
$('.isChecked').click(
function()
{
if ( $(this).is(':checked') )
{
$(this).show();
}
else
{
$(this).hide();
}
}
);
}
);
</script>
</head>
<body>
<form>
<input type="checkbox" name="program" class="isChecked"/>
<input type="checkbox" name="program" class="isChecked"/>
<input type="checkbox" name="program" class="isChecked"/>
<input type="checkbox" name="program" class="isChecked"/>
</form>
</body>
I think the problem in your code can come from the $(document).ready() handler that waits for the entire DOM to be loaded before binding action listener to it.
What's more, your jquery code wasn't working for me. My version seems to work, but once checked box hidden, the user cannot handle them anymore.
Otherwise, I think doing some Doctrine requests in your template is a very bad idea.
Good bye !

Grid/List view with image size

I have problem with change images size in posts (after click on the buttons grid/list).
these are the buttons that should (after click) change $value to true or false (that scale images):
<div class="products_look">
<input type="button" class="view_list" onclick="" value="List" />
<input type="button" class="view_grid" onclick="" value="Grid" />
</div>
and this is the php functions that generated grid or list view in the posts:
<?php
if($value == true) {
echo image_products_grid();
}
else {
echo image_products_list();
}
?>
What I need to insert in onClick tags that after clicking on the button returned php $value (true or false)?
Why not use a parameter in the URL? Something like this:
<div class="products_look">
<input type="button" class="view_list" onclick="window.location = 'display.php?type=LIST'" value="List" />
<input type="button" class="view_grid" onclick="window.location = 'display.php?type=GRID'" value="Grid" />
</div>
And then on your PHP page:
<?php
if($_GET["type"] == "GRID") {
echo image_products_grid();
}
else {
echo image_products_list();
}
?>
Is this the type of solution that you are looking for? It's not terribly elegant, but your question is a little unclear so I hope this helps.

Change a buttons value if parameters are met, jQuery, PHP, Sessions

I have the following button:
<input type="button" count='<?php echo count($_SESSION['children']);?>' name="children" class="add_child" value="Add Another Child"/>
On default when the form loads (with a clean session) there is no input for children, so the button should read "Add a Child".
If there is a text field present with the name children[] then it should just display: "Add another Child".
How would this be done ?
I am using php / jquery / sessions for the fields here is the code for it:
$('.add_child').click(function(){
var attrName = $(this).attr('name');
var count = $(this).attr('count');
$(this).attr('count', (parseInt(count)+1))
var input = $('<input />');
input.attr('type','text')
input.attr('name',attrName+"["+count+"]" )
$('.children_form').append($('<li />').append(input));
$('#content li:odd').addClass('alt');
})
<?php
if(isset($_SESSION['children'])) {
foreach($_SESSION['children'] as $index=>$child){ ?>
<li>
<?php echo "<input type='text' name='children[{$index}]' value='{$child}'/>";?>
</li>
<?php } }?>
Try this out with the code you have already:
$('.add_child').click(function(){
//code...
$(this).val('Add Another Child');
})
and the php for the input:
<input type="button" count='<?php echo count($_SESSION['children']);?>'
name="children" class="add_child"
value="<?php echo (isset($_SESSION['children'])?
'Add Another Child':'Add a Child');?>"
/>
