PHP - Help Properly Converting A Javascript Function To Php..
I have this function which is javascript and I need to convert it to php..
Code: [Select] function US2dec(myUS) { if (myUS.toLowerCase() == 'even') { myUS = '100'; } var myDec; myUS = parseFloat(myUS); if (Math.abs(myUS) < 100 || isNaN(myUS)) { myDec = NaN; } else if (myUS > 0) { myDec = 1 + myUS / 100; } else { myDec = 1 - 100 / myUS; } return myDec.toFixed(8); } I came up with this php version and it seems to work but I'm no expert with math functions.. I was hoping somebody who's a bit more familiar with these functions could check it over quick.. Code: [Select] function US2dec($myUS) { if (strtolower($myUS) == 'even') { $myUS = 100; } $myDec = 0; $myUS = floatval($myUS); if (abs($myUS) < 100 || !is_numeric($myUS)) { $myDec = 0; } else if ($myUS > 0) { $myDec = 1 + $myUS / 100; } else { $myDec = 1 - 100 / $myUS; } return number_format($myDec,8); } Thanks!! Similar TutorialsHi, Since upgrading to php 5.3 i have a line of code on my site that is giving me a depreciated error. The line of code is as follows: $data=eregi_replace(">"."[[:space:]]+"."<","><",$data); I've got as far as knowing i need to change it from eregi_replace to preg_replace but i can't for the life of me work out where to put any backslashes etc, if any. Is there a formula for working this type of thing out? Every example i see has backslashes and $1's all over the place. Do i simply do this "/ and this /" after and before every double quote? Or is it not as simple as that? Things never are are they! Please could an expert on here offer me any assistance. This is an important line of code(i think) so i didn't want to experiment as i would normally do, i need to get this right first time as i don't know what will happen if i get this wrong. Cheers. Here's the code with the function that won't work! Code: [Select] $itemsRaw = explode(" ", $player['inventory']); foreach ($itemsRaw as $inv){ $contents = explode("-", $inv); if(strlen($contents[0]) > 0 && strlen($contents[1]) > 0 && $contents[1] > 0) echo getItemName($contents[0]) . " (" . number_format($contents[1]) . ")<br />"; } Here's my function: Code: [Select] function getItemName($id_raw){ $id = $id_raw - 1; $q = $db->query("SELECT * FROM items WHERE id = $id") or die(mysql_error()); $f = $db->fetch_assoc($q); return $f['name']; } It stops the page when it gets to that point and won't load anything else and the function doesn't even work with it :/ What's wrong with it? If anything.. Okay im trying to make it so when some is on this link ("?serv=del&id=$ID") it displays a portlet of a yes/no form. onces yes/no is picked it goes to ("?serv=del&id=$ID&del=true"). I have no idea if im doing this right or if theres a better way of doing it. But trying to fix this problem has almost made me throw my computer threw my window. Thanks in advanced. <?php if(isset($_GET['serv']) && $_GET['id'] == $serverid && $_GET['del'] == 'true') { if($_POST['ture']) { mysql_query("DELETE FROM `notifications` WHERE `id`='$msgid'"); Echo "<center>Message Deleted</center>"; } else { Echo "<center>Message delete request has been canceled.</center>"; } } elseif(isset($_GET['serv']) && $_GET['id'] == $serverid) { ?> <div class="usercp_body"><!-- UserCP Notification Manage Start --> <div id="dash_chart" class="portlet" style="width:100%;margin: 0 auto;"> <div class="portlet-header"> <h4><center>All Servers For <?php echo $username; ?></center></h4> </div> <div class="portlet-content"> <form action="manage.php?serv=del&id=<?php echo $serverid; ?>&del=true" method="post"> <input type="submit" class="bgbtn blue" value="Yes" name="true" /> <input type="submit" class="bgbtn blue" value="No" name="false" /> </form> </div> </div> </div> <?php } ?> I have a simple php script that updates my sitemap automatically. However, when you click the link to the sitemap at www.bomstudies.com/sitemap-xml.php - the last mod date is showing 1969.

I am using the following PHP code to create a table for a form
<tr><td><img src="images/gate_<?php echo $rider_row['colour'];?>.png"/> <input name="id[]" type="hidden" value="<?php echo $rider_row['id'];?>"/></td><td><input readonly="readonly" name="rider[]" value="<?php echo $rider_row['rider_name'];?>" class="txtfield"/><br /> <select name="substitute[]" class="txtfield" style="display:none"> <option value="">-----------------</option> <?php foreach($reserves as $key=> $value): echo '<option value="'.$value.'">'.$value.'</option>'; //close your tags!! endforeach; ?> </select></td><td><select name="points[]" class="txtfield" onchange="test();"> <option value="">-----------------</option> <?php foreach($scoring as $key=> $value): echo '<option value="'.$key.'">'.$value.'</option>'; //close your tags!! endforeach; ?> </select><br/> <select name="subpts[]" class="txtfield" style="display:none"> <option value="">-----------------</option> <?php foreach($scoring as $key=> $value): echo '<option value="'.$key.'">'.$value.'</option>'; //close your tags!! endforeach; ?> </select> </td></tr>On changing the value in the field called points[], if certain values are selected then two other fields are to be displayed, I am using the following function
<script>
function test() {
if (document.getElementByName('points[]').value == 'F2 || E || N') {
document.getElementByName('substitute[]').style.display = '';
document.getElementByName('subpts[]').style.display = '';
} else {
document.getElementByName('substitute[]').style.display = 'none';
document.getElementByName('subpts[]').style.display = 'none';
}
}</script>
I am getting an error saying getElementByName is not a function, I know I can do this by getElementById, but the fields do not have ID and not sure how I can give them a unique ID when echoing them from the database.
If someone could just give me some pointers I would be very grateful
Hi Everyone. I'm working on a form, that allows the user to select the country / county / area where they are from. I am doing this using: - mysql database store the locations in - PHP OOP, to pull this information from the database - AJAX/Javascript to only show the next dropdown, once the first dropdown has been selected. Example: select country then the county dropdown will appear, select county then the area/town will appear. However, the first drop down for country is placed directly on to the page. So the javascript works fine. but the second dropdown is placed in to a PHP function, and the javascript seems to no longer want to work. CODE: Code: [Select] //////////////// CODE FOR COUNTRY /////////// if(isset($_REQUEST['country'])) { echo ' <div class="labelleft">County / State:</div> <div class="fieldleft"> <div > <select name="county" id="county" onchange="javascript:AJAXQuery("lib/search.php?town="+this.value, "tw", "")"> <option value="0">Select County</option> <option value="0">-------</option>'; $countyList = Area_county::find_country_id($_REQUEST['country']); foreach($countyList as $countyLists){ $county_id = $countyLists->id; $county_list = $countyLists->county; echo '<option value="'.$county_id.'">'.ucwords($county_list).'</option>'; } echo ' </select> </div> </div> <div class="clear"></div>'; } Any ideas? Thanks Hi guys, I am having a tough time executing the code inside the javascript. Everything is working fine with the Php code and I am able to see the output of variable myValue too..

This bit of code actually does work, I just want to check that this is the best/proper/most efficiant way of doing it. Basically i'm calling a PHP function that uses the javascripts prompt function, then returning the value that the user types in back to PHP. Most probably easier to show you.

That website uses javascript for pagination, splitting data across 3 pages.

I want to pull all that data with PHP but how do I emulate the Javascript AJAX call in my code so I can get all that data instead of just the first page? Even if I could just call that function and then parse the information it returns to me. Thanks.
This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=348942.0 Hi All,
My page contains a JS function that enables to print the content of a DIV, and contains also a jQuery Autocomplete textbox that does not belong to that DIV.
Here is the JS for printing the div
function printContent(el){
var restorepage = document.body.innerHTML;
var printcontent=document.getElementById(el).innerHTML;
document.body.innerHTML = printcontent;
window.print();
document.body.innerHTML = restorepage;
}
The HTML attached to it is
<div id="div1">DIV 1 content...
</div> <button onclick="printContent('div1')">Print Content</button>
If the user clicks the button to print the content of the DIV, they cannot afterwards make use of the Autocomplete textbox.
It seems the issue occurs with any kind of jQuery UI, not just autocomplete.
In this case, the HTML of the Autocomplete is
<div class="ui-widget">
<label for="tags">Tags: </label>
<input id="tags" />
</div>
and the script
$(function () {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl"
];
$("#tags").autocomplete({
source: availableTags,
minLength: 0,
delay: 0
});
});
jquery-ui-1.10.3.custom.css, jquery-1.9.1.js and jquery-ui-1.10.3.custom.js are used.
Any idea of how to keep the jQuery UI functional after the div-printing JS function has been used ?
Thanks for your help.
