[php switch if isset]

yes that was what i was looking for lol thank you

[php switch if isset]

i know theres a way but i just forget. i want to do a switch function.

 

switch ($_GET['page']) {
    case 0:
        include 'page';
        break;
    case 1:
        include 'page1';
        break;
    case 2:
        include 'page2';
        break;
    default:
        include 'page';
}
?>

 

just like that but if there is no $_GET page i just want it to do the default. instead of doing if isset GET page do switch else default page. i just want it to be simpler by doing something like switch(isset$_GET etc.

[what the HECK is going ON??!?!]

ok at least i know im not crazy lol. i use godaddy. ill ask them about it but i doubt they will be able to do anything. maybe i should just change servers. any suggestions?

[what the HECK is going ON??!?!]

i tried what you said. it shows the array. it shows the array with the data SOMETIMES just like it did with the form. this is absouletly crazy. someone please try it out yourself. put data in the text field and submit it. it works. then go back refresh form do it again. tell me if it doesnt work sometimes. and also on page 2. resend data. once resent it usually doesnt show data.

 

http://frozenasfs.com/form/formp1.php

 

i even tried it on two different website servers. and this is all thats on each page exactly.

 

formp1.php

<form method="post" action="formp2.php">

<input type="text" name="text" id="text">

<input type="submit">

</form>

 

formp2.php

<?php

 

if (isset($_POST)){

var_dump ($_POST);

}else{

 

echo "No POST data!";

 

}?>

 

 

 

 

 

 

[what the HECK is going ON??!?!]

this is so frustrating. i know my coding isnt wrong. the most basic form doesnt even work (always).

 

formp1.php

<form method="post" action="formp2.php">
<input type="text" name="text" id="text">
<input type="submit">
</form>

 

formp2.php

<?php echo $_POST['text']; ?>

 

heres the thing it works SOMETIMES. i send the form and it shows. i go back and do it again and it doesnt. another time it shows another time it doesnt. all the same text input to. i put the number 1.

 

what could possibly do this? its not my browser i tried 2 different browsers. it makes no sense what so ever someone give me something PLEASE

[select form option auto select fix]

no i havent that will work but is there anyway i can make it call a function if a form field is selected already on refresh if its on the one that needs a function

[select form option auto select fix]

i have a select form. when they click a certain option a js function is used to change something. the problem is when the page is reloaded that option is automatically still selected even when i have another one auto selected. this makes it so the option that is supposed to cause a function is already selected and the function isnt done so it messes things up. how can i make it so i can change the default selected option or auto load a function if its going to be selected on refresh.

 

(im not sure how confusing that was or not)

[grouping database data]

oh ok i thought you could use order by and group by together. i wanted it to group but also in order by date. i can choose just one then if both isnt possible. thanks =]

[grouping database data]

i have a column with different data examples

 

ex1

ex2

ex1

ex2

ex1

ex2

 

when i select it i want to group them by the name so they will come out like this..

 

ex1

ex1

ex1

ex2

ex2

ex2

 

i thought thats what "group by" was for but it only brought up one of the data each like this

 

ex1

ex2

 

how can i do this? thanks!

[WHAT THE HECK! Ajax request only working once in a while??]

it works 9 outta 10 times now. so uhh i guess i can deal with it for now. if you have any other suggestions let me know thanks for your help =]

[WHAT THE HECK! Ajax request only working once in a while??]

i put that and i tried it and i was like wow that worked. and i kept switching to different options and it worked like 9 times in a row then it started not working again and sometimes even the data is from a different table which makes no sense. its the other ajax i have in the javascript for the chat.

 

so thanks i think its a little bit better now? lol but still same problem just not as bad haha wow this makes no sense any other suggestions?

[WHAT THE HECK! Ajax request only working once in a while??]

part of the form:

 

 

        <td width="100%"><select name="select_workout_routine" id="select_workout_routine" onchange="javascript:showWorkoutInfo(this.value);"><option value="0" selected>-----Choose Your Full Body Routine-----</option><?php$sql = "SELECT id, workout_name FROM user_workouts WHERE workout_type = 'full' AND user_id = '0'";$result = dbQuery($sql);while ($row = dbFetchAssoc($result)){extract($row);echo "<option value=\"" . $id . "\">";echo $workout_name;echo "</option>";}?></select><br><br></td>

 

 

the javascript:

 

 

function showWorkoutInfo(str){if (str=="")  {  document.getElementById("workoutRoutines").innerHTML="";  return;  }if (window.XMLHttpRequest)  {// code for IE7+, Firefox, Chrome, Opera, Safari  xmlhttp=new XMLHttpRequest();  }else  {// code for IE6, IE5  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");  }xmlhttp.onreadystatechange=function()  {  if (xmlhttp.readyState==4 && xmlhttp.status==200)    {    document.getElementById("workoutRoutines").innerHTML=xmlhttp.responseText;    }  }xmlhttp.open("GET","getInfo.php?id="+str,true);xmlhttp.send();}

[WHAT THE HECK! Ajax request only working once in a while??]

This is so frustrating, I don't understand why this might be happening. I have a select form input that uses onchange to send a ajax request to show the data.

 

It works. Then I click again it doesnt work, click another select option it works, then back to the other works, then the next doesnt then doesnt then doesnt then does... sorry it just seems so random there are only 2 options right now and they work every like 4 clicks going back and forth on average.

 

There has to be an explaination, how can I fixed this. I googled it and read something about caching which makes no sense and I added the headers like it said:

 

 

header("Expires: Sun, 19 Nov 1978 05:00:00 GMT");

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

header("Cache-Control: no-store, no-cache, must-revalidate");

header("Cache-Control: post-check=0, pre-check=0", false);

header("Pragma: no-cache");

 

to the php page. Please save me from this frustration please.

[get web root]

Your problem could be that you're accessing the web page without the www. and the AJAX request includes the www In that case you should either force www or no www or do something like this:

 

xmlhttp.open("GET","http://" + location.host + "/lib/getMessage.php",true);

 

tytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytytyty

[open with url]

xmlhttp.open("POST", 'lib/sendMessage.php', true);

 

the url needs to change on every page. that will work for just the home page.

other pages would need ../lib/sendMessage.php because they are in different folders.

 

how can i make it so it works no matter what page they are on.

i tried putting the domain like http://www.domain.com/lib/sendMessage.php but that does not work!

 

i thought i could use my web root from my php function and <?php  echo WEB_ROOT; ?> but that wont work. there has got to be a way and i want it so you dont have to type in the url and it gets the url itself like my web_root function does so it can be used with different websites

 

PLEASE HELP!!

[get web root]

nevermind it doesnt even work when i put the full url in.

 

its an ajax thing

 

xmlhttp.open("GET","lib/getMessage.php",true);

 

that works for only the front page. but if i go to a different folder it wont work because the url changes.

 

if i put

xmlhttp.open("GET","http://www.domain.com/lib/getMessage.php",true);

that doesnt work tho!

 

why??? i know this is more ajax/js now but please help

[get web root]

i use a php function to get "http://www.domain.com"

 

when i go to my javascript file and try to go <?php echo WEB_ROOT; ?> it doesnt work. so is there a way to use php in a javascript

 

if not is there a way to get the website with js?
