[RESOLVED] Tis an IF STATEMENT again

[dcjones]

Hi All,

I got a lot of help with this code snippet yesterday but I need some more please.

This is the code I am working with which work great, but I want to extent it.

<?php 
for ($i = 1; $i <= 8; ++$i) { 
    if (!empty($row_lost['secure_id_' . $i])) { 
        echo $row_lost['secure_id_' . $i] . "<br />\n"; 
    } else { 
        break; // Do not display remaining variables as well. 
    } 
} 

?>

I have 8 feilds which contain string data yes or no.

The code above displays the content of feilds "secure_id_1 to secure_id_8". I now would like to display the following:

If secure_id_1 has data then (in the next col same row) display the word "yes".

I have played around with this all day with no luck. ButI am learning all the time.

Can anyone please advise me.

[stewartship]

try something like:

if($row_lost['secure_id_' . $i] != ' '){ // i.e. is not blank contains yes or no
echo 'yes<br>';
}

to achieve the column affect you could surrond with html table tag and then relevant <tr> and <td> 's to give row and columns

[dcjones]

and thank you for your reply

I have used the changes you kindly provided but its not exactly what I am trying to do.

I have 8 vatiables each of which hold 0 or 1.

secure_id_1_l
secure_id_2_l
secure_id_3_l
secure_id_4_l
secure_id_5_l
secure_id_6_l
secure_id_7_l
secure_id_8_l

I also have another 8 variables which hold numbers.

The code I am using displays the content of those variables if they hold content,

the variables are

secure_id_1
secure_id_2
secure_id_3
secure_id_4
secure_id_5
secure_id_6
secure_id_7
secure_id_8

What I need to happen is: example

if "secure_id_1" is not empty AND "secure_id_1_l" IS = 1, then echo to screen.

Waht I have so far is:

<?php
for ($i = 1; $i <= 8; ++$i) {
if (!empty($row_lost['secure_id_' . $i])) {
echo $row_lost['secure_id_' . $i] . "<br />\n";
} else {
 break; // Do not display remaining variables as well.
}
?> 

Can this be done.

Any help with this from anyone would be great.

if (!empty($row_lost['secure_id_' . $i]) && $row_lost['secure_id_' . $i.']_|' == "1") {
echo $row_lost['secure_id_' . $i] . "<br />\n";
} else {
break; // Do not display remaining variables as well.
}

Hi again and many thanks for all your time

The code gives an error

Parse error: parse error, unexpected ')', expecting ']'

<?php
for ($i = 1; $i <= 8; ++$i) {
if (!empty($row_lost['secure_id_' . $i]) && $row_lost['secure_id_' . $i.']_|' == "1") {
echo $row_lost['secure_id_' . $i] . "<br />\n";
} else {
break; // Do not display remaining variables as well.
}
?> 

Thanks again

Hi and sorry to be a aoin in the neck

The code gives another error

Parse error: parse error, unexpected $

I have had a look through it but can not see why this error should happen

[bradgrafelman]

Missing '}' brace for the for() statement.

As mentioned in the FAQ.

Hi to all who have replied and hello to those who have not.

I am still having big problems with this code.

If I echo the following variables I get a results of:

secure_id_1_l = 1
secure_id_2_l = 1
secure_id_3_l = 1
secure_id_4_l = 0
secure_id_5_l = 0
secure_id_6_l = 0
secure_id_7_l = 0
secure_id_8_l = 0

secure_id_1_l = 111111
secure_id_2_l = 222222
secure_id_3_l = 333333
secure_id_4_l = 444444
secure_id_5_l = blank
secure_id_6_l = blank
secure_id_7_l = blank
secure_id_8_l = blank

so I know there is content in them. If I use the code below it reurns empty feilds.

Can anyone see where I am going wrong with this:

<?php
for ($i = 1; $i <= 8; ++$i) {
if (!empty($row_lost['secure_id_' . $i]) && $row_lost['secure_id_' . $i].'_|' == "1") {
echo $row_lost['secure_id_' . $i] . "<br />\n";
} else {
break; // Do not display remaining variables as well.
}
}
?>

Many thanks

[stewartship]

Think the label you have created here:

if (!empty($row_lost['secure_id' . $i]) && $row_lost['secure_id' . $i].'_|' == "1") {

should be

if (!empty($row_lost['secure_id' . $i]) && $row_lost['secure_id' . $i.'_|'] == "1") {

i.e you closed the ] before you have created the full label

let me know

[dcjones]

Hi all,

I am still having big problems with this.

If I echo all the variables I get the following results:

echo $row_lost['secure_id_1']; // result = 1, which is correct 
echo $row_lost['secure_id_2']; // result = 1, which is correct 
echo $row_lost['secure_id_3']; // result = 1, which is correct 
echo $row_lost['secure_id_4']; // result = 1, which is correct 
echo $row_lost['secure_id_5']; // result = 0, which is correct 
echo $row_lost['secure_id_6']; // result = 0, which is correct 
echo $row_lost['secure_id_7']; // result = 0, which is correct 
echo $row_lost['secure_id_8']; // result = 0, which is correct 

echo $row_lost['secure_id_1_l']; // result = 111111, which is correct 
echo $row_lost['secure_id_2_l']; // result = 222222 which is correct 
echo $row_lost['secure_id_3_l']; // result = 333333, which is correct 
echo $row_lost['secure_id_4_l']; // result = 444444, which is correct 
echo $row_lost['secure_id_5_l']; // result = NULL, which is correct 
echo $row_lost['secure_id_6_l']; // result = NULL, which is correct 
echo $row_lost['secure_id_7_l']; // result = NULL, which is correct 
echo $row_lost['secure_id_8_l']; // result = NULL, which is correct 

When I run the complete script I get no data displayed.

for ($i = 1; $i <= 8; ++$i) {
if (!empty($row_lost['secure_id_' . $i]) && $row_lost['secure_id_' . $i.'_|'] == 1) {
echo $row_lost['secure_id_' . $i] . "<br />\n";
} else {
break; // Do not display remaining variables as well.
}
}

I have had so much help but I am still at a dead end.

Hi again,

I have tried to make this easy to follow by taking all the other stuff out of the script.

This is what I have, but with errors:

<?php
$secure_id_1_l = 1;
$secure_id_2_l = 1;
$secure_id_3_l = 1;
$secure_id_4_l = 0;
$secure_id_5_l = 0;
$secure_id_6_l = 0;
$secure_id_7_l = 0;
$secure_id_8_l = 0;

$secure_id_1_l = 111111;
$secure_id_2_l = 222222;
$secure_id_3_l = 333333;
$secure_id_4_l = 444444;
$secure_id_5_l = 0;
$secure_id_6_l = 0;
$secure_id_7_l = 0;
$secure_id_8_l = 0;

echo $secure_id_1; // result = 1, which is correct
echo $secure_id_2; // result = 1, which is correct
echo $secure_id_3; // result = 1, which is correct
echo $secure_id_4; // result = 1, which is correct
echo $secure_id_5; // result = 0, which is correct
echo $secure_id_6; // result = 0, which is correct
echo $secure_id_7; // result = 0, which is correct
echo $secure_id_8; // result = 0, which is correct

echo $secure_id_1_l; // result = 111111, which is correct
echo $secure_id_2_l; // result = 222222 which is correct
echo $secure_id_3_l; // result = 333333, which is correct
echo $secure_id_4_l; // result = 444444, which is correct
echo $secure_id_5_l; // result = NULL, which is correct
echo $secure_id_6_l; // result = NULL, which is correct
echo $secure_id_7_l; // result = NULL, which is correct
echo $secure_id_8_l; // result = NULL, which is correct 

for ($i = 1; $i <= 8; ++$i) {
if (!empty($secure_id_ . $i) && $secure_id_ . $i.'_|' == 1) {
echo $secure_id_ . $i . "<br />\n";
} else {
break; // Do not display remaining variables as well.
}
} 
?>

[stewartship]

for ($i =0; $i<8; $i++) { // your loop should start from 0-7 (giving the 8 fields)

// your secure_id_$i have fields 1 + 0 not other way round so need to reverse

if ( (($row_lost['secure_id' . $i])== 1) && (($row_lost['secure_id' . $i.'_|'] != ' ')) ){

echo $row_lost['secure_id_' . $i] . "<br />\n"; // think you proabbly want to display the other results here no?

// so change to

echo $row_lost['secure_id' . $i. 'l'];
echo '<br>';

} // to the if

else
{
break; // Do not display remaining variables as well.
}

} // to the for

i would change the naming of your variables in order to make the distinction more viewable i.; secure_id.$i and secure_id_result.$i makes the programming easier.

let me know how it goes

[stewartship]

try the following (NB i have kept the query and display order in your original so change as i suggested before if you want to display the other results):

for ($i=0; $i<8; $i++) {
if ( (($row_lost['secure_id' . $i])==1) && (($row_lost['secure_id' . $i.'|'] != ' ')) ){
echo $row_lost['secure_id' . $i];
echo '<br>';
} else {
break; // Do not display remaining variables as well.
}
}

[dcjones]

Hi there.

I have changed the code to

for ($i=0; $i<8; $i++) {
if ( (($row_lost['secure_id_' . $i])==1) && (($row_lost['secure_id_' . $i.'_|'] != ' ')) ){
echo $row_lost['secure_id_' . $i];
echo '<br>';
} else {
break; // Do not display remaining variables as well.
}
}

There is no output.

I did as you rightly suggested, I changed "secure_id?L" to "secure_id?result" which does make it easier to follow.

Again if I echo all the variables in single rows they produce the requiered result.

What do you think?

I know your time is limited so I am very thankful.

[scrupul0us]

wait... its an 'L' and not a pipe '|'... that changes things

for ($i=0; $i<8; $i++) 
{
     if (($row_lost['secure_id_' . $i]==1) && ($row_lost['secure_id_' . $i.'_L']==1))
     {
     echo $row_lost['secure_id_' . $i];
     echo '<br>';
     } 
     else 
     {
     break; // Do not display remaining variables as well.
     }
} 

change that 'L' to whatever its supposed to be... whether its lowercase or upper, pipe or not

try not to use the letter 'L' solely in coding.... its easily gets mis-interpreted as a pipe

[stewartship]

scrupulous is correct the 'l' can be misinterpreted let me know if anything changes

[dcjones]

Hi Guys,

At last some output, all thanks to your help.

The only problem I am having with the output is:

If "secure_id_1" has data and "secure_id_1_result" = 0

and "secure_id_2" has data and "secure_id_2_result" = 1

then I wanted the data for "secure_id_1" to be displayed.

The code now looks like

<?php
for ($i = 1; $i <= 8; ++$i) {
if (!empty($row_lost['secure_id_' . $i]) && $row_lost['secure_id_' . $i.'_result'] == 1) {
echo $row_lost['secure_id_' . $i] . "<br />\n";
} else {
break; // Do not display remaining variables as well.
}
} 
?>

[stewartship]

Hi so if i am getting this right you want to search through and if you get a result == 1 (instead of 0) you wish to display the previous data set, if this is the case then you need:

if(!empty($row_lost['secure_id' . $i]) && $row_lost['secure_id' . $i.'result'] == 1){
echo $row_lost['secure_id' . ($i-1)] . "<br />\n";
}

which will display ($i-1) results i.e. the previous results
