Code: [Select] $lastblock = current( $s0 ); print_r($lastblock); The problem is i won't know the $row seeing as it is in a while loop. Solution? I am trying to pass a php variable to javascript but it's not working. This is the "sketch" of my code. <?php $url="asset/go/"; ?>
<!DOCTYPE html>

var url ='<?php echo json_encode($url); ?>';

}

</html>
As it is now, it comes with the output below: <?php echo json_encode($url); ?> If I remove the quotation around the php in d jQuery, it throws an error in syntax. Also both codes are located in the same file named test.php Thanks in advance. Edited April 18 by Abel1416
Hi All, I've been trying to access xml data from an API feed, but it needs a Variable to be passed to an include file without a form. the include is at the header of the page. in the code below, i'm trying to retrieve the variable $project_add from the $xml_2 feed. $proj_add_ID comes from another feed and is being passed ok.
foreach ($projects_1 as $proj_1) {
$job_no =$proj_1['job_no'];
$job_name =$proj_1['job_name'];
$job_status =$proj_1['job_status'];
$job_staff =$proj_1['job_staff'];
$job_due =$proj_1['job_due'];
$clr_1 = $colors_1[$job_status];
if ($err_2) {
echo "cURL Error #:" . $err_2;
} else {
$_POST['job_id']= $job_no;
$xml_2=simplexml_load_string($response_2) or die("Error: Cannot create object");
$proj_add = $xml_2->xpath("CustomFields/CustomField[ID ='$proj_add_ID']");
foreach($proj_add as $item_2) {
$project_add = "$item_2->Text";
}
echo "<div class='row no-gutters'>";
echo "<div class='col-sm bg-white border rounded'><a href='managejob.php?job_id=$job_no' class='text-left ml-1'><strong>$job_no</strong></a></div>";
echo "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'>$job_name</p></div>";
echo "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'></p>$project_add</div>";
echo "<div class='col-sm-2 bg-white border rounded'>" . state_dropdown_1($job_no, $job_status, $clr_1) . "</div>";
echo "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'>$job_staff</p></div>";
echo "<div class='col-sm-2 bg-white border rounded'><form action='CALL_API_PUTTaskDate.php' method='POST'>"
. "<input type='hidden' name='task_ID' value ='". $jdata['task_ID'] ."'>"
. "<input type='hidden' name='est_min' value ='". $jdata['est_min'] ."'>"
. "<input class ='form-control bg-white text-dark font-weight-bold' type='date' name='start_date' value='" . date('Y-m-d', strtotime( $jdata['display_date_1'] )) . "' onchange='this.form.submit()'>"
. "</form></div>";
echo "<div class='col-sm bg-white border rounded'><p class='text-left ml-1 mt-1'><strong>" . date('d/m/Y', strtotime( $jdata['display_date'])) . "</strong></p></div></div>";
}
The include file is like this
/ collect Custom Felds
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// collect value of status input field
$job_no = $_REQUEST['job_id'];
}
if (isset($_POST['job_id'])) {
$job_no = $_POST['job_id'];
}
if (isset($_GET['job_id'])) {
$job_no = $_GET['job_id'];
}
$curl_2 = curl_init();
curl_setopt_array($curl_2, array(
CURLOPT_URL => "https://api.xxx.com/job.api/get/$job_no/customfield?apiKey=xxx&accountKey=xxx",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"Accept: */*",
"Accept-Encoding: gzip, deflate",
"Cache-Control: no-cache",
"Connection: keep-alive",
"Host: api.xxx.com",
"Postman-Token: xxx",
"User-Agent: PostmanRuntime/7.17.1",
"cache-control: no-cache"
),
));
$response_2 = curl_exec($curl_2);
$err_2 = curl_error($curl_2);
curl_close($curl_2);
The problem is the variable $job_no isn't getting passed to CURLOPT_URL so it's not retrieving the data required. i need to be able to retrieve this data without submitting a form as it's in a foreach loop and the Id is specific to each iteration. is there a way to do this? I have been able to achieve this by putting the include within the div tags that it will be displayed but it just slows down everything too much and hangs. Any help will be much appreciated. Kind regards, Michael Bennington. i've been programming in PHP for years, and have done a substantial amount of work on applications of this nature. this problem has me stumped, not because i can't fix it (i did), but because i have no idea what the problem is. there are hundreds of lines of code involved here, so i'll break it down into a post-friendly format. take this for example, and forgive any typos. it's late, and i've been beating my head against this for over two hours... =\ this is from my form: Code: [Select] /* ... numerous form fields being passed as $_REQUEST arrays */ <input type="hidden" name="option_id[]" value="<?php print $query_result->option_id; ?>" /> /* a couple hundred more lines */ here's the DB update handler: Code: [Select] if (!empty($_REQUEST['option_name'])) { foreach ($_REQUEST['option_name'] as $k => $v) { if ($v != '') { $option_id = $_REQUEST['option_id'][$k]; $option_name = $_REQUEST['option_name'][$k]; $option_price = $_REQUEST['option_price'][$k]; $option_desc = htmlentities($_REQUEST['option_desc'][$k], ENT_QUOTES); if (!$option_id = '') { $sql_options = "UPDATE table SET" . " option_name = '" . $option_name . "', option_price = '" . $option_price . "', option_desc = '" . $option_desc . "' WHERE option_id = '" . $option_id "'"; if (!$query_function($sql_options)) { $error = true; } } else { $sql_options = "INSERT INTO table (option_name, option_price, option_desc)" . " VALUES ('" . $option_name . "', '" . $option_price . "', '" . $option_desc . "')"; if (!$query_function($sql_options)) { $error = true; } } } } } the above code doesn't post to the database because the $option_id variable returns a null value. however, if i replace the $option_id variable where i build the query string with $_REQUEST['option_id'], it works just fine. Code: [Select] /* in relevant part */ $sql_options = "UPDATE table SET" . " option_name = '" . $option_name . "', option_price = '" . $option_price . "', option_desc = '" . $option_desc . "' WHERE option_id = '" . $_REQUEST['option_id'] . "'"; needless to say i was infuriated by having spent a couple of hours to come to this conclusion. i only used the variables in the first place because i need to expand the function that this lives inside and i don't want to have to type $_REQUESTs over and over. the only thing i can think is that it might be a type issue. the data is coming out of the mysql table from an INT field and being placed into the value for the hidden field straight from the row collection. would forcing a variant data type by not strongly typing my variable have caused this problem? i haven't tested the theory because i'm still too ticked off to open my code editor. i'm bouncing this off the community and posting my experience in the hope that it might help someone who comes after. I actually asked a question here yesterday and decided to try a different route with it. What I am doing is passing an email variable entered from my home page on to www.dollapal.com/offerlist.php. I'm wanting this page to be a complete list of all of my entries in my surveys table. The email variable needs to be appended to the end of every link. I got that to work, but what I want to do now is display that information for every record in my 'surveys' table. Right now I am using the random function, which I'm sure is wrong, but I'm not sure what function to be looking for. Is it possible to use a foreach function here to echo each record? If so, I'm not sure how exactly to call the foreach() function in this case. I believe my two problems lie in the random and foreach functions, but I'm not sure how to correct them. I've attached a little chunk of code that I'm working with. I'm not sure if I'm completely off base here, or if I'm close to achieving my desired result. Please let me know if you require more information. This forum has been amazing to me so far. Thank you all for your help! In my main script I set $errorArray with values when required survey questions go unanswered. The ne code that checks for missing required values is working perfectly, and right before I pass $errorArray to a function which rebuilds the survey questions - this time with the error messages - I do a var_dump($errorArray) and that array has errors in it as expected. But while my function that re-builds the survey questions gets called and does indeed re-build the survey questions, the $errorArray isn't getting pased for some strange reason? (I'm not sure if i have ever passed an array to a function before.) In my function I have...
function generateSurveyItem($dbc, $questionNo, $questionID, $surveyResponseArray=NULL, $errorArray=NULL){
}
When I var_dump($errorArray) at the top of the function, and submit a blank form, I end up with a blank page and a file path to my PHP script ending with... /public_html/utilities/function.php:3010:null
Questions: 1.) What is happening?
2.) I thought =NULL in the parameter list just meant that the argument is "optional"?
3.) I am able to successfully pass $surveyResponseArray to this function, so what is up with $errorArray?
P.S. When I run things, and submit an empty form - thus no "required" fields get completed - the survey gets re-displays, and any values chosen are "sticky", but my error messages should also be displayed to let the user know what is mising, and that is the part that isn't working? This has to be something silly stupid to fix... Edited February 16 by SaranacLake Is it good practice to put an oop object in session variable I know how to use $$ and ${} to use variable variables, but how would I get the same functionality out of a variable that is storing an object name? I have a function that is passed the name of an array of objects. As you can guess, that name will change based on which portion of the program is calling the function. How would I use variable variables of objects in this instance? Would it just be: Code: [Select] $this->${$objArrayName}->threadName = etc; ? To make sure I'm not being misunderstood, I have 3 arrays of objects (replies, mainThreads, and stickies) and depending on which name I pass the function, I want it to use $this->replies OR $this->mainThreads OR $this->stickies to apply properties of those objects to. Thanks for any help. -Adam Can someone explain to me how this is done? Hi!
I have this code above:
// Submit Data to ncbi.
// Sends form's data to classController.php
function NCBI_submit_data()
{
$formData = $('#blastx_form').serialize();
$php_method = 'ncbi_request';
$finalData = $formData + "&php_method=" + $php_method;
$aR = ajaxReq('POST','../../classes/classController.php',$finalData,'json');
console.log($aR);
}
// General Ajax function
function ajaxReq($method,$url,$data,$dataType)
{
$.ajax({
type: $method,
url: $url,
async: 'false',
data: $data,
dataType: $dataType,
success: function(json, textStatus, jqXHR)
{
return json;
},
error: function(jqXHR, textStatus, errorThrown)
{
console.log('Ajax call error: '+jqXHR.status+' '+errorThrown)
}
});
}
Server returns a json object and i want to save it in aR variable.
But console.log($aR); returns undefined
Any idea on how to fix it ?Hi guys im in the middle of optimizing code.. Code: [Select] $sql = "SELECT * FROM sa_enemystats WHERE username='$username'"; $res = mysql_query($sql); while ($row = mysql_fetch_assoc($res)) { $enemy['current_health'] = $row['current_health']; $enemy['current_skill'] = $row['current_skill']; $enemy['level'] = $row['level']; $enemy['damage'] = $row['damage']; $enemy['evade'] = $row['evade']; $enemy['accuracy'] = $row['accuracy']; $enemy['speed'] = $row['speed']; $enemy['luck'] = $row['luck']; echo 'debug: variables synced with db table'; }I know that the setting of these variables are messy and can be done in a better way... but how? I have tried foreach and copying other's code for an array copy but it lead no where. Then again my syntax could be wrong... I used something like Code: [Select] foreach ( $enemy[$value] as $row => $value) { $enemy[$value] = $row[$value]; } Could someone help me crack this issue.
