manipulating string output from serialize function

billspeg

hi anybody else go to phpworks i was there whew it got pretty deep with all those classes at phpworks in toronto.

well anyways here is my problem i hope some one can help i have a multi-checkbox from a form that i store in an array from the array i serialize all the data into one field in mysql then i access the database field as part of an array of objects when i echo the results i get this
s:325:"a:1:{i:0;a:13:{i:0;s:16:"Consumer is Fine";i:1;s:12:"Cannot Sleep";i:2;s:13:"Sleep is Good";i:3;s:10:"Not Hungry";i:4;s:13:"Good

i have tried str_ireplace and some goofy regex not that regex is goofy just how i applied it it looked ugly i am sure. but i am unable to manipulate this string at all why i am'b new to string manipulation and this is a new experience with the arrays. i am now going to include relevent code bytes help please.

$consumer_progress[] = $_POST['consumer_progress'];
$field_name = serialize($consumer_progress);
(much code...)
$query="UPDATE client_db_doctor_client SET consumer_progress ='$field_name'

access page.php

$progress = $object['consumer_progress'];

tried some string manip here didnt work

output from echo

s:325:"a:1:{i:0;a:13:{i:0;s:16:"Consumer is Fine";i:1;s:12:"Cannot Sleep";i:2;s:13:"Sleep is Good";i:3;s:10:"Not Hungry";i:4;s:13:"Good

what exsactly do you wish to do with the serialised array

when you retrieve it in access.php

billspeg

could i not manipulate the string with eregi_replace () but i could not manipulate the string i just want to store it in a variable and echo the contents not all the (i)(s) before it

sidney

if you dont want all the i and s why dont you just implode the
array and store the imploded array in data base

billspeg

hi i tried implode and it is supposed to output a string so it should of worked but all i get is "array" as the ouput of the echo.

do i need to for loop or when loop through the array with implode or what could be wrong please??

thanks

sidney

$output=array('tom','bill','sue');
$outpstring= implode(',',$output);
echo $outputstring;

unless i am missing something here :
why not use the unserialize function? 😕

sidney

i thought that but i think billspeg wants to output a string

its not really clear what billspeg wants

i tryed asking but never got a clear answer

hi i am trying to take multiple choices from an checkbox array and store them in database field one field and then echo out the array on a output page what would be the best ay to go about doing this with premade php functions. i amb sorry if i confuse you. my application will be extensive and many simple things together create complication this project is the largest and most extensive application i have ever created and i am sure this will not be the first problem that i encounter thanks

sidney

implode would be the simpleist option if your having problems show the code and we will help ther

saying that it would be best to save the individaul form fields in there own field in the database.

maybe even there own table

this will make editing the data and displaying alot easier further down the line

rather than pulling a comma dilimited list and trying to grab just one field or trying to compare what they entered with somthing

billspeg

$var = array[$object];
$var2 = implode($var);

query to database $var2

output page

query to database

access object array

$var2 = object['database_field'];

echo "subject ' ".$var2." ' ";

using implode $var2 just echo the string "array" none of the values of the array that was imploded to a string are shown

duhhh how do i do it please

billspeg

thank you for the advice sid i will take your suggestion seriously but a new table seems like a awful lot of typing for my tired hands. i guess i will have to go that way and thanks again for being here for me

sidney

$var = array[$object];
is not right it would cause a parse error

is $object the array

can you show me how you created the array as what yo have shown is not clear

and using imlode should be easy as long as you feed it an array

some examples
$var=implode(', ',$object);

$var=implode(', ',$array[$object]);

as the array need to have a $ sign

using you original post code

$consumer_progress[] = $_POST['consumer_progress']; 
$field_name = implode(',',$consumer_progress); 
(much code...) 
$query="UPDATE client_db_doctor_client SET consumer_progress ='$field_name'

billspeg

hi turns out i confused php when i originally posted the array in the checkboxs i had made an array variable consumer_progress[]

when i posted i goofed by calling the post variable as an array again ex:
consumer_progress[] = $_POST['consumer_progress'];

i removed the [] brackets from the variable assignment the second time it was enough to call the array once in the form i guess implode works like a charm now sid be talking to ya look for my posts will ya and thanks agai
