php - Help on how to continue with code that verifies a registered user and updates mySQL -

-

When a user registers, the script sends an email to verify its account. When clicking on the link, the script gets the token 

  $ token = mysql_real_escape_string ($ _GET ["token"]);   
 and what I have to do  
  if ($ token! = '') {Mysql_query ("updated member SET verified = '' WHERE verified = ' $ Token '"); } ($ Token! = '') {$ Result = mysql_query} ("updated members have been verified by SET"}   
  or   
  = '' WHERE verified = '$ token' "); if ($ result) {} else {}}   
 What is my purpose that success on user Or the unsuccessful message is to be resonated when it succeeds, then  verified  will be empty.  
 What is the proper way to do it with the examples above?  
 Should I check if the tokens should be updated in DB  
 Thank you.   
 
 
 If your presence is present, But does not exist in your account, it updates your records, which does not exist or does not match. You should run something like this:  
  if ($ token ! = '') {$ Result = mysql_query ("SELECT COUNT (*) members where verified = '$ token'"); while ($ line = mysql_fetch_row ($ result)) {$ records = $ row [0]; } If ($ record == 0) {echo 'no results'; } Elseif ($ record == 1) {echo 'matching you'; Then update the record. }}   
 edit  
 while the loop was changed back, 0 rows did not think about counting back

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
