PHP - Write "str_replace" Before It's In The Link

Hey,

So on my profile page I have a lot of info such as Name, Birthday, City, Country, Status etc...
Its set up like this...

Name:  $loggedInfo[Name]<p/>
Birthday: $loggedInfo[Birthday]<p/>
City: $loggedInfo[City]<p/>
Country: $loggedInfo[Country]<p/>
Status: $loggedInfo[Status]<p/>


The problem is is that if the user doesnt fill out this info then there is a blank space on their profile. How can I go about having it so if there is no data for say Country, on their profile there will be a link and it will say "Edit this!" and that link can just go to edit profile.

Pretty much I dont want to do this for everything...

if($loggedInfo[Name] != "")
{
     echo"$loggedInfo[Name]";
}else{
     echo"<a href='edit_profile.php'>edit this!</a>";
}



Thanks,
Sean

Hi guys

I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words.


$find = "left";
$replace = array("up","down","forward","backwards");
$text = "left left left left";

echo str_replace($find,$replace,$text);


The Output is: array array array array

Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? 

Thanks

cant work out this mysql syntax error
"operation":"medupdate","medid":"","name":"ibo","medyear":"5","medmonth":"21","medday":"1","recuser":1,"SuccFail":"fail","SuccFailMessage":"error occured You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '''WHERE med_id=' at line 2","ResultData":""}

Code: [Select]
$sql="update metodology set med_description='".$req['name']."',
  med_year='".$req['medyear']."', med_month='".$req['medmonth']."', med_day='".$req['medday']."', med_recorddate= now(), med_recorduserid= 1'";
  $sql.= " WHERE med_id=".$req['medid'];

Working on changing sessions to be stored in db. Using example I found on Internet.

Works for the most part, however it's driving me nuts  that my username is being stored as data|s:6:"bertha"; vs. just the username bertha.

I've read where the session_set_save_handler is "serializing" the data by default.

In any case, I want to get at the username entered to ensure I keep my users logged in, etc. I've tried to "unserialize" the entry but it always returns false!

MANY THANKS!!

Hi.

A quick one:

How do I write this in PHP?

if (this variable don't contain "@")
echo "This is not a valid email address";

Regards Morris

I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

Just started.  I am pretty sure composer.json wasn't changed.  journalctl doesn't show anything.  Maybe Doctrine related, however, nothing seems to help.

Any ideas?

Hi, I currently have an if, elseif, else program that starts off with

Code: [Select]
if( $v_name == "" || $v_msg == "" )
echo "something"
how do I turn this into a switch?

but the very next elseif I have

Code: [Select]
elseif( strcspn( $_REQUEST['msg'], '0123456789' ) == strlen( $_REQUEST['msg'] ) )
echo "something"

is it possible to turn this into a switch with 2 different strings like that to evaluate?

Hello, I have 2 questions...

1. Do you know of any good and easy php breadcrumb solution?

2. I have recently learned how to use PHP to make a navigation Active based on what page I am on (see below).  If I am on the "currentPage" "contact.php" it will show it active...
But, what I also want to do is have the main nav active on a sub-nav page.  Is it possible to have 2 or more page referenced?  Something like ($currentPage == 'contact.php' AND 'contact_form.php')  Where both pages would make the link appear active and highlighted.

   <ul>
      <li><a href="contact.php" <?php if ($currentPage == 'contact.php') {echo 'id="here"';} ?>>Contact</a></li>
      <li><a href="about.php" <?php if ($currentPage == 'about.php') {echo 'id="here"';} ?>>About Us</a></li>
      <li><a href="careers.php" <?php if ($currentPage == 'careers.php') {echo 'id="here"';} ?>>Careers</a></li>
      <li><a href="services.php" <?php if ($currentPage == 'services.php') {echo 'id="here"';} ?>>Services</a></li>
      <li><a href="index.php" <?php if ($currentPage == 'index.php') {echo 'id="here"';} ?>>Home</a></li>
   </ul>

Thank you in advance for your help

hello,

I was wondering what is the point of writing

for a dropdown: <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?>

or for a checkbox/ radio button: <?php if ($_POST['cb/radioID'] == "value") { echo "checked"; } ?>

I guess it's for after submit, if there is any error, the values filled will still be echoed in the inputfield, or am i wrong?

But then if that is true, i have a php search box where i use AJAX object to to send all the input they filled in after submit. But after pushing submit the inputted values remain.

I guess when using AJAX to send the information i don't need  <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> in my html forms?


Little confused Can maybe somebody bring clearness

Hey guys!
I have the following doubt:

I have a php file that does the following alongside with other code not displayed he

$fp = fopen("emails.txt", "w");

It opens a txt file called emails.txt that is in the same folder where the php is saved but how do I tell $fp = fopen("/folderbefore/emails.txt", "w"); ??

In other words, how do I write the path on the script that the emails.txt is located in a previous folder where the php file is located??

Thanks in advance for your help
Cheers!
