This is the problem I'm having with code:
- I have a function that creates an updating bar;
- I have a function that creates a loop, each number of loop makes some other stuffs and the same number represent the progress of the bar (from 1 to 155);
- this loop works when user make a "search" on the site for "all" countries;
- BUT user can also make a "search" only choosing 1-5 different countries;
- this way we have a function that makes the PROGRESS BAR, another one that makes the PROGRESS PART of the BAR that should understand how to progress.
So the point is that I don't know how make the function for progress bar to interpret the situation in order to know that user choosed only some countries and not "all" countries (the option will post to the function some "numbers of the loop" like "3", "4", "56"... corresponding to choosed country) - and this is the easy part (with maybe isset($var)).
The next hard part is that after that it will be called the PROGRESS BAR function with those "country-numbers" so that if you choose "Canada-USA-France" the numbers will be "34-12-45" and the progress bar will write "34%-12%-45%". But it's incorrect because if you have 3 options choosed, it should be 33%-66%-99% (and not 34%-12%-45%)...
What I don't know is how to make that function understand that everytime the function receive the "country-number", and it comes from user choice different from "all", the function should get that number and modify it (and this can be made with an array) in order to adapt it to the correct bar progression so that if you have: 34, than 12 than 45, the function should understand that the 1st time 34 should become 33, the 2nd time 12 should become 66 and the 3rd time 45 should become 99 (or 100)...
Here is the code part of interest:
1. receiving _POST and verifying it:
function getData() {
$a = strtolower($_POST["CountryOne"]);
$b = strtolower($_POST["CountryTwo"]);
$c = strtolower($_POST["CountryThree"]);
$d = strtolower($_POST["CountryFour"]);
$d = strtolower($_POST["CountryFive"]);
$numPost = count($_POST);
if ($numPost == 0) {
echo("<p class='Verify'>Select an option to start search...<br></p>");
} else {
echo "<div class='Verify' id='progressbar' style='width:620px;height:16px'></div>
<div class='VerifyBar' id='information' style='width'></div>";
};
2. Jump to next part after checking it user choosed "all" or "some countries" - here is the loop:
function loopNum($x) {
$i = 0+$x;
$y = $x+3;
for ($x = $i; $x <= $y; $x++) {
$iscountryID = ("$country".$x."");
createUrl($iscountryID);
} if($y != 155) {
return loopNum($x);
} else if($y < 155) {
echo("<font size='2' face='Tahoma, Geneva, sans-serif' style='font-variant: small-caps' color='#FF0000'><i>ERROR: unxepected data extraction interruption</font></i><br>");
} else {
echo("<font size='2' face='Tahoma, Geneva, sans-serif' style='font-variant: small-caps' color='#00CC00'><i>FINISHED: data extraction ended</font></i><br>");
}};
3. than it makes a lot of other stuff and call progress bar function
function completeBar($iscountryID) {
//***** PART UNDER CONSTRUCTION WHERE I NEED HELP *****
$countryOne = strtolower($_POST["CountryOne"]);
$countryTwo = strtolower($_POST["CountryTwo"]);
$countryThree = strtolower($_POST["CountryThree"]);
$countryFour = strtolower($_POST["CountryFour"]);
$countryFive = strtolower($_POST["CountryFive"]);
if (($countryOne !== 'all') and ($countryTwo !== 'all') and ($countryThree !== 'all') and ($countryFour !== 'all') and ($countryFive !== 'all')) {
$numQuery = array("$countryOne","$countryTwo","$countryThree","$countryFour","$countryFive");
foreach ($numQuery as $value) {
if(is_numeric($value)) {
$j++;
}}; // AT THIS POINT I WOULD KNOW HOW MANY VALUES IN THE ARREY ARE DIFFERENT FROM "ALL" AND "NO_COUNTRY" OPTIONS AND SO ARE NUMERIC VALUES
//***** FROM HERE I DUNNO HOW TO PRECEED *****
} else { //the next part works with "all" option choosed
if ($iscountryID < 155) {
$i = $iscountryID;
$percent = $i."%";
$pxbar = 4*$i."px";
$percentage = round((($pxbar*100)/624),0); //bar is 624px long
// Javascript for updating the progress bar and information
echo '<script language="javascript">
document.getElementById("progressbar").innerHTML="<div style=\"width:'.$pxbar.';background-color:#ddd;\">'.$percentage.'% </div>";
document.getElementById("information").innerHTML="'.$i.'/155 country(s) processed... loading your data, hold on..."</script>';
// This is for the buffer achieve the minimum size in order to flush data
echo str_repeat(' ',1024*64);
// Send output to browser immediately
flush();
sleep(1);
} else if ($iscountryID == 155) { //so on loop complete
$i = $iscountryID;
$percent = $i."%";
$pxbar = 4*$i."px";
$percentage = round((($pxbar*100)/624),0);
echo '<script language="javascript">
document.getElementById("progressbar").innerHTML="<div style=\"width:'.$pxbar.';background-color:#ddd;\">'.$percentage.'% </div>";
document.getElementById("information").innerHTML="'.$i.'/155 country(s) processed... loading your data, hold on..."</script>';
echo str_repeat(' ',1024*64);
flush();
sleep(1);
// Tell user that the process is completed
echo '<script language="javascript">
document.getElementById("progressbar").innerHTML="<div style=\"width:'.$pxbar.';background-color:#ddd;\">100% </div>";
document.getElementById("information").innerHTML="<div>Process completed, all countries verified...</div>";
document.getElementById("information").style.color="green";
</script>';
echo str_repeat(' ',1024*64);
flush();
sleep(1);
}
}};
Ah... I've tried to make the following working but the problem is that with the following, I'll have the function updating the bar getting values from the array too fast. Using the VAR sent from the rest of the file, I'll have an updating bar that follows the updating output of the server.
function partialBar() {
$countryOne = strtolower($_POST["CountryOne"]);
$countryTwo = strtolower($_POST["CountryTwo"]);
$countryThree = strtolower($_POST["CountryThree"]);
$countryFour = strtolower($_POST["CountryFour"]);
$countryFive = strtolower($_POST["CountryFive"]);
$numQuery = array("$countryOne","$countryTwo","$countryThree","$countryFour","$countryFive");
foreach ($numQuery as $value) {
if(is_numeric($value)) {
$j++;
};
};
if ($j == 1) {
$iscountryID = 155;
completeBar($iscountryID);
} else if ($j == 2) {
$iscountryID = array("78","155");
completeBar($iscountryID[0]);
completeBar($iscountryID[1]);
} else if ($j == 3) {
$iscountryID = array("52","104","155");
completeBar($iscountryID[0]);
completeBar($iscountryID[1]);
completeBar($iscountryID[2]);
} else if ($j == 4) {
$iscountryID = array("39","78","117","155");
completeBar($iscountryID[0]);
completeBar($iscountryID[1]);
completeBar($iscountryID[2]);
completeBar($iscountryID[3]);
} else if ($j == 5) {
$iscountryID = array("31","62","93","124","155"); //these numbers are the corresponding loop number in other to get 20%-40%-60%-80%-100% from the completeBar() function
completeBar($iscountryID[0]);
completeBar($iscountryID[1]);
completeBar($iscountryID[2]);
completeBar($iscountryID[3]);
completeBar($iscountryID[4]);
} else echo ("<div class='Verify'>Something went wrong!</div>");
};
